Used struts, brakes, and switches have to be the top things to never purchase used unless the switches have next to no wear on them. I've purchased window/door lock switches for the Stealth at something like $20-$30 for each side, but requested detailed close-ups to ensure they weren't used to the point where the lettering was fading. Considering a new driver's side was $180 and they didn't even have the passenger side listed, I think I did quite well. There are a ton of people always looking for used tires and while there are some good deals out there for just about brand new tires, a lot of them don't really work out too well for the buyer, given what he/she paid for them. I seem to see a lot of people looking for used vacuum lines, too. Those things are dirt cheap new, so why risk getting cracked/brittled ones?!!!
