The situation
Michael is 47, an orthopedic surgeon at a large hospital system, and lives in Chesterfield, a well-heeled St. Louis suburb. His commute is 22 miles each way to the hospital, but his real driving comes from three-hour surgical stints scheduled across multiple locations plus weekend recreation. Annual mileage sits at 15,000. His current vehicle is a 2018 Audi Q5 with 105,000 miles; he plans to replace it within the next six months. He has narrowed his decision to two Genesis models: the 2026 Genesis GV60 Standard AWD and the 2026 Genesis GV70 2.5T AWD. Both are compact luxury SUVs from the same brand, both are AWD (essential for Missouri winters), both are available at the same Chesterfield dealership. Michael is a cash buyer at this price point and plans to hold the vehicle 5 years before turning it over.
The GV60 starts at $52,525 for the base Standard RWD, but Michael needs AWD to match the GV70's capability profile, so his effective GV60 price is $55,525. The GV70 2.5T AWD comes in at $48,985. This produces a $6,540 MSRP premium for the EV — not enormous by luxury standards, but real. Michael is not indifferent to environmental considerations, but at this price point his decision has to work economically. He is willing to enroll in a utility rate program and be disciplined about charging behavior if the payback justifies the effort.
Three things about St. Louis and Missouri shape the analysis. The first is the Missouri EV decal fee. Because EV drivers do not pay gasoline tax at the pump, Missouri imposes a $150 annual Special Fuel Decal Fee on electric vehicles at registration, plus a $9 processing fee — approximately $159 in year one and $150 annually thereafter, totaling $759 over 5 years. This is a real structural cost that most EV cost analyses miss because it does not appear at the point of purchase. It shows up on the DMV registration form. For Michael, this is money he would not pay if he bought the GV70.
The second is Ameren Missouri's Overnight Savers rate program. Ameren Missouri offers a residential time-of-use rate targeted at EV owners and heat pump adopters that dramatically discounts overnight charging. The off-peak window runs 10 PM to 6 AM. Base off-peak generation-only rates run as low as $0.05-$0.06/kWh, but when riders and localized taxes are layered on, the true all-in effective cost falls into the $0.075 to $0.095 per kWh range — among the lower documented rates in the Drive Economics library. Peak weekday rates hover around $0.16/kWh during summer months, so charging discipline is essential; Michael would need to enroll in Overnight Savers and use his charger's scheduling function to defer all charging to the 10 PM-6 AM window. Standard Ameren Missouri residential blended rate for comparison sits around $0.125/kWh.
The third is the Ameren Missouri residential Level 2 charger rebate. Ameren offers up to $500 for approved Level 2 charger installations at residential locations. Michael's Chesterfield home has a garage with existing 240V service for a workshop; a Level 2 installation runs roughly $1,350 in this market. Net of the Ameren rebate, the actual charger cost lands at $850. The rebate offsets most of the MO EV fee, which is worth naming explicitly — these two Missouri-specific factors roughly cancel each other over 5 years.
The question this case explores is: when the operating math clearly favors the EV but the resale market punishes low-volume luxury EVs more severely than established luxury gas vehicles, how should a buyer think about the divergence between cash flow and total cost of ownership? The answer reveals something the library has not surfaced this explicitly before.

The 5-year math
Two GV60 scenarios shown side-by-side against the GV70 baseline. Scenario 1 assumes Michael enrolls in Ameren Missouri's Overnight Savers rate and disciplines his charging to the 10 PM-6 AM window. Scenario 2 assumes he stays on standard residential (default if he does not enroll). Both use actual St. Louis retail gas at $3.99/gallon.

Assumptions: St. Louis metro regular gasoline at $3.99/gal (verified 2026-09-04). Ameren Missouri Overnight Savers rate at $0.085/kWh all-in effective (midpoint of $0.075-$0.095 all-in range covering base rate plus riders and localized taxes); assumes 100% disciplined 10 PM-6 AM charging via home Level 2. Ameren Missouri standard residential blended rate at $0.125/kWh. GV60 efficiency averaged at 33 kWh/100mi (modestly worse than EPA 30.3 to reflect real-world luxury EV consumption patterns). GV70 2.5T AWD at 22 MPG combined per EPA. Missouri EV decal fee is $150/year at annual registration plus $9 first-year processing fee, totaling $759 over 5 years. Ameren Missouri residential charger rebate of $500 applied to standard $1,350 Level 2 installation. Depreciation reflects Drive Economics's market-observed retention models: GV70 at ~50% total loss over 5 years reflects established luxury SUV segment retention; GV60 at ~62% total loss reflects heavier depreciation typical of low-volume niche luxury EVs (Genesis EV resale data is limited given the vehicle's short market history; this estimate uses comparable low-volume luxury EV segment data). Insurance from density-and-MSRP model for St. Louis metro. Maintenance from make and category baselines; GV60 advantage reflects fewer mechanical service items. No federal EV credit (expired September 30, 2025). Missouri has no state EV purchase rebate. See methodology.
What the analysis reveals
Cash flow and total cost of ownership tell different stories, and this is the first case in the library where the divergence is decisive. On pure cash outlay over 5 years, the GV60 comes out $3,510 to $4,500 ahead of the GV70 depending on rate plan enrollment. That is real money — not enormous, but meaningful. But when depreciation is included in total cost of ownership, the GV60's advantage compresses to $117 to $1,107. The two vehicles are essentially tied on TCO. The reason: the GV60 loses roughly $10,000 more in resale value over 5 years than the GV70 does. That $10,000 depreciation delta absorbs almost the entire operating cost advantage the EV builds up through fuel savings, maintenance savings, and rate plan discipline.
The Missouri EV decal fee and Ameren charger rebate roughly cancel each other. This is worth naming plainly because most EV cost analyses miss the state EV fee entirely. Missouri charges $150 per year at annual registration to offset lost gas tax revenue, plus a $9 first-year processing fee — $759 over 5 years for a GV60 owner. Ameren Missouri's residential charger rebate offers up to $500 for approved Level 2 installations. Net effect: the two Missouri-specific factors offset each other with $259 of net drag remaining on the GV60 side. Not decisive, but not zero either. Buyers running their own analysis should account for both, not just the incentives.
Overnight Savers enrollment saves Michael $990 over 5 years compared to standard residential. This is the largest variable within his direct control after purchase. The all-in rate difference of $0.04/kWh at his 4,950 kWh annual consumption translates to $198/year in savings, or $990 over 5 years. He would need to enroll in the Overnight Savers program (an active step through Ameren's customer portal) and use his charger's scheduling function to defer all charging to the 10 PM-6 AM off-peak window. Both are easily achievable but require awareness that the default rate is materially worse. The savings do not fundamentally change the outcome — the GV60 wins on cash either way — but they meaningfully improve the margin.
The generalizable finding: at the luxury tier, depreciation is the dominant variable. Fuel-cost savings, rate plan discipline, and equipment rebates all matter, but they operate at a scale of $1,000-$5,000 over 5 years. Depreciation deltas at the luxury tier operate at $8,000-$15,000 over the same period. The buyer who plans to hold the vehicle 8-10 years will see the depreciation curves flatten and the operating cost advantage compound — a longer-hold buyer likely comes out clearly ahead with the GV60. The buyer who turns over vehicles every 3-5 years faces the depreciation punishment full-force. Michael's stated 5-year horizon sits at the point where the two effects roughly cancel. His decision becomes less about spreadsheet math and more about non-financial preferences: the GV60's technology package, silent luxury driving experience, or the GV70's larger cargo area and established resale market for eventual sale.
What could shift the analysis
- The GV60 depreciation estimate is the largest uncertainty in the analysis. Genesis EV resale data is limited given the vehicle's short market history — the GV60 launched for the 2023 model year, and 5-year-old examples do not yet exist in volume for reliable price discovery. This case models 62% depreciation over 5 years based on comparable low-volume luxury EV segment data. If Genesis EV depreciation ends up closer to established luxury norms (55% loss), the GV60 saves approximately $3,900 more over 5 years and wins TCO decisively. If it depreciates like other niche EVs (70% loss), Michael loses an additional $4,400 and the GV70 wins TCO by roughly $3,300-$4,300. This is genuine uncertainty, not sensitivity theater — nobody knows for sure yet how a 2026 Genesis GV60 will hold value through 2031.
- Hold duration is the strongest lever for buyers who can tolerate longer ownership. A 7-year hold sees the depreciation curve flatten while operating savings continue to accumulate. Rough estimate: at 7 years the GV60 pulls ahead of the GV70 by $2,500-$4,000 on TCO under Overnight Savers, and by $1,500-$2,500 on standard residential. At 10 years the operating cost advantage compounds further while depreciation on both vehicles converges toward similar residual values. Michael's stated 5-year horizon is the worst case for a niche luxury EV; extending to 7-8 years transforms the analysis materially.
- St. Louis gas price volatility swings the outcome. St. Louis retail gas has ranged from $3.20 to $4.90 over the past 24 months. A $1.00/gallon swing translates to roughly $3,400 over 5 years for the GV70 — comparable to the entire cash advantage the GV60 currently holds. Sustained gas prices above $4.75 shift TCO clearly to the GV60. Sustained prices below $3.25 largely erase the cash advantage entirely. Buyers making a 5-year decision now should consider their view of gas price trajectory. St. Louis's Midwest location and refinery access historically keep prices below coastal averages, but not below inland manufacturing state averages.
- Overnight Savers enrollment is not automatic — default behavior loses money. Michael must actively enroll in the Overnight Savers program through Ameren Missouri's customer portal. If he buys the GV60 and never enrolls, he defaults to standard residential and gives up $990 over 5 years. This is not a hypothetical concern; consumer research consistently shows that only 30-40% of EV owners in TOU-eligible utilities actually enroll in their utility's EV rate program. The default rate is a real risk, and the calculator scenarios above assume active enrollment. Buyers who know they are the "set it and forget it" type should model the Standard Residential scenario as their realistic case.
- Charging behavior outside the home would materially change the analysis. This case assumes 100% home charging for Michael's daily usage patterns. A luxury EV buyer with access to workplace charging (free or discounted) could shift the electricity cost profile substantially. Conversely, a buyer whose usage patterns require frequent DC fast charging on regional trips (say, 20% of miles at Electrify America pricing of ~$0.48/kWh) would add roughly $2,000 to 5-year electricity costs, largely erasing the cash advantage. St. Louis has moderate DC fast charging density along interstate corridors but limited workplace charging outside of specific downtown employer initiatives. Michael's use case as a suburban hospital-based physician skews strongly toward home charging.
- The GV60 is a smaller vehicle than the GV70. The GV60 seats 5 comfortably but has meaningfully less cargo space than the GV70 (approximately 24 cubic feet vs. 29 cubic feet with seats up, expanded to 55 vs. 57 cubic feet with seats folded). Both are compact luxury SUVs, but the GV70 sits in a more directly competitive class with the BMW X3 and Audi Q5 while the GV60 competes with smaller crossovers. A buyer whose usage patterns require the extra 5 cubic feet of cargo capacity would face a real capability trade-off, not just an economic one. Michael's use case (family of four, hospital-focused driving) fits either vehicle; a buyer with larger cargo needs may find the GV60 constraining.
- Federal EV credit reinstatement would flip the analysis decisively. The $7,500 federal EV credit expired September 30, 2025, and is not currently claimable. If future legislation reinstates it for the Genesis GV60, the tax credit would eliminate almost all of the GV60's cash-cost disadvantage upfront and produce a $5,000-$7,000 TCO advantage even after depreciation. This is an unpredictable political variable, not a planning consideration, but worth naming as the largest potential shift.
- Non-financial factors matter at the luxury tier. The GV60 offers 350 kW DC fast charging (adds ~200 mi of range in 18 minutes when available), integrated regenerative braking with paddle-shifter control, and a genuinely silent cabin. The GV70 offers a proven engine platform, larger cargo, higher tow rating, and an established used-car market for eventual resale. These are not economic variables but they are the actual decisions luxury buyers make. If the pure economics come out roughly tied, the tiebreaker should be the driving experience preference. This case does not adjudicate that tiebreaker.
