I think that's why you have to have an emotional connection to your car at some level. If you're looking for a reason to quit, it's too easy to find one.
I'm shocked at how many people whose cars have issues say that they don't have a service manual...
I have a service manual but it doesn't actually match my car :) 1962 plymouth service manual and it has flanged axles in it but not tapered.. flanged didn't even exist at the time.. great book :)
I came close to trashing/selling mine a few times.. easy to hate them when they spend years on jackstands... mainly why i had to drive before winter.. all re-energized again.
