$6K sounds like a pretty solid deal with those service records, those will be worth their weight in gold. Follow Mike's advice and get it checked out though.

I bought my '02 with great service records. I've driven it daily for almost 20K miles, all I've done are the front brakes and battery. I do some mild off-roading and take it up to the mountains for skiing but have never run into a problem that I would have needed CDL.
