I've had fewer cars than that but my experience is similar. Mostly older, youngest was a 2007 make. Take care of fluids, tires and brakes, and they've just work

I've had fewer cars than that but my experience is similar. Mostly older, youngest was a 2007 make. Take care of fluids, tires and brakes, and they've just worked. Worst breakdowns I've had have been flat tires, that's a half hour downtime until the spare is switched in. Unexplained five hour "reboots" sounds like a joke. That's not a car, it's a toy.
