Maybe don’t drive a customer’s vehicle over 200 miles and they will return your equipment when you leave it in their car instead of assuming it was a gift.

Should get at least 300k before needing any major repairs, most likely more if you’re keeping up with maintenance. Most parts are pretty cheap, too, so you could also just fix whatever breaks and keep on going.

My friend had a 2012 prius, spun a bearing around 360k miles, engine blew at 370k. $1600 for a used engine (replaced it himself) and had 650k on it when he sold it. Been Toyota and lexus lover ever since.
