It depends.......this year I spent probably close to two full weeks working on my car to fix rust issues and replace my transmission and rear brakes. BIG year for repairs. Normally its a lot less, just a trans fluid change and a couple oil changes etc....probably works out to less than an hour a week over the course of a year.

I also do work on all of my family's cars....so between all of them I spend a fair amount of time working on them.....however, I get paid for the majority of that.....so its not really wasted time at all.
