Here's a quick list of what I've had to replace on my car from between the time I bought the car (about 90,000 miles) to now (114,000 +). Unless I say otherwise, everything was replace because something was broke or truly worn out; I'm an if it aint broke, don't fix it type of person.
Timing belt (routine maintenance)
Thermostat housing (leaking)
One rear bearing (it went from perfect to the wheel wobbling all over within three days)
Parking brake cable (you can thank NYS salt rust for that)
Front struts (more for an upgrade than because they were that bad)
Both front lower control arms (completely worn out)
Sway bar links (One of the joints has popped out so the sway bar wasn't held by anything anymore)
And that all I can remember right now. I haven't had any trouble with the engine and a large part of the stuff listed above was contributed to by the rust we get from road salt.
