My friend and I have started tinkering on our cars together.
He’s got an early 90s 525i BMW and I’ve got a 2000 SR5 Toyota 4Runner.
The engineering of my Toyota is so much simpler and easier to work on than his BMW. But his BMW has given us a lot more practice, if you know what I mean ^_^
"Big Money Waster" is what we used to call them. They are notorious for electronic faults in particular. They're just very complicated, which electric cars aren't.
Funny enough, my 2007 BMW had so many issues and cost so much to maintain i used to call it a “wallet burning machine”
