TL;DR - they're cheaper. The batteries lose charge - range drops from 260 miles to 200 miles by the 300,000 mile mark

"Tesloop’s Model 3 fleet will see total costs (which includes depreciation, or how much value the car loses before its sold) fall as low as $0.18 to $0.25 per mile after driving past 500,000 miles. That’s less than premium brands such as Mercedes, and even lower than the $0.32 to $0.35 for standard sedans."

Bwwwwaahhahaha!  I shoot for $0.10 per mile.  I used to get it with the large majority of my cars. Currently, I'm at about $0.12 on Louise's Honda, approx $0.15 on my 2015 Grand Caravan, and close to $0.10 on my beater 2010 Grand Caravan.

The BEST one I've had was a Ford Tempo my kids drove. When it fell below $0.05, I quit tracking.

>you don't bother fixing dents and scratches

IIRC, I pocketed $1.6k from the last fender-bender (wasn't my fault).  I popped out the crushed plastic shroud within an hour. Took about 20 minutes if you knew how.  Not a bad rate of pay.

My per mile calc does not include fuel & tires. It does include major maintenance.  So, when assessing a car for purchase, I take the delivered price and multiply it by 10.  That's how many miles I'm expecting out of it.
