That's a specious argument. Most gasoline powered cars today will be performing as good as new at 100k miles with minimal attention beyond regular oil changes and a new set of spark plugs -- certainly, you don't need a complete motor replacement that early in. Likewise, any car with 100k miles, EV or not, will have a pretty worn interior, need a new suspension, be showing wear on its paint, have very out of date electronics and safety features, and be out of fashion style-wise (and yes, that matters when it comes to price. Just ask the designers of the Pontiac Aztek).

Quality ICE cars are pretty trivial to run a long time. I drive a 2003 Honda SUV, which just hit 230,000 miles. I've probably put an average of $500 annual repairs for the last 6-7 years. Mostly drivetrain stuff that wears out like CV joints, sway bars, etc.

If you buy a electric car, you're not doing it to save money. The optimal ROI remains a 12-24 month old car with a certificatation program that you keep for 8-10 years. I'd rather do that and have $30k in the bank than futz with electric cars and unknown service lives.
