if you maintain it and replace parts properly the first time you can almost keep in as new condition but yeah everything gets old, you cant fight time itself. Its a personal judgment, if your over it move on but the time will come when the new car will start to get old too. I guess its a test to see how much you love your car...lol
Maybe ive been lucky with my car and in the 8 yrs ive had it the only major thing to die was power window motor and the battery. the 100k service replaced alot of what needed to be replaced including exhaust manifold studs and the clutch. I get a good feeling fixing things that i can fix on my car, kinda makes it just a bit newer in my mind..ha
I guess the one think that makes me feel the car is old is seeing so many of them on the road and how cheap they are compared to 8 yrs ago.
