I have a 2002 Sub LT 1500 that I bought new. I purchased an aftermarket warranty that ran out in December. I now have 72,000 miles. I have been/am involved in a lot of other automotive forums (Porsche, Audi, Subaru) that have been very helpful. I am pretty handy at some things on my cars, but my knowledge of my Suburban in minimal. I figured that joining this group would help me maintain my car and cut through a lot of the dealer BS.
