I purchased a Trek 2200 in 2003. I rode it a while (500 miles?) and then my knees decided to be mean to me. The bike sat in my garage, out of sunlight but still getting temperature cycles (40-85 in Nor Cal weather). I started riding the bike again in 2009. I just added oil to the chain. No problems. After 1000 miles in, I replaced the tires since they seemed a bit dry on the edges and I didn't want to risk tire failure. I had a 2 mph "fall" that resulted in a broken shoulder. No real bike damage, just some twisting of shifters. I then got the $80 tune up and the shifting felt even smoother. As I have to replace parts, I'll look for the sweet spot where you get better quality for the price, but aren't paying extra $ to shave off 100gm of weight.
