It's unfortunate but true

No classic or old car is immune to time. Seals rot, metal rusts, and wear happens even if not used for decades. Time and pressure gets everything eventually, and unfortunately 90's and 2000's cars that have a 3800 like mine are dying and falling apart. They'll still run well over 300k miles with good maintenance but interior plastics crack, warp, wiring cracks, electric motor grease in windows, seats, ac etc gums up and causes failure. Rubber lining cracks. My car only has 85000 miles on it, but time has gotten the interior and some other things outside the engine. I've replaced just about everything under the hood. I wish the gov would let us build our own cars without so many regulations.
