If you don't live where rust eats vehicles they do not have to wear out. Some maintenance is needed from time to time but it is a lot cheaper than buying new.

My work truck is a 2000 Chevy. I've had it since it was new. 320,000 miles on it now and it runs great, I would not hesitate to to head out cross country with it tomorrow. I put a trans in it a couple of years ago, cost me 2K for a rebuilt (including the R&R). Other than that, over its lifetime it has had a power steering pump, spider gears in the diff, a radiator, an alternator, an AC compressor, and batteries, tires, belts and hoses. Company keeps trying to give me a new one but I refuse, I tell them this is a science project now.
