I bought my 2001 GMC Jimmy SLS used in 2004. It was a dealer buy-back because of electrical problems. I have 118,000 miles on it with no serious mechanical repairs. Yes, it has needed brakes, but that's normal. Had a serious vibration problem which was found to be missing washers in the hood hinges. A cheap repair and it's quiet. I like this vehicle a lot. My only regret is that it isn't 4 wheel drive.
Interior is roomy and well thought out. Instrumentation is easy to see. Front leg room is very good. Back folds down flat for cargo/pets.
Getting in and out of the back seat can be a real pain. But once you're in there, it's comfortable.
