Dylan is right, they are known for transmission problems. That is the first thing I did to mine was add a transmission cooler. As far as the TBSS? It is fun, practical, nice to travel in, turns a few heads, personally I really enjoy owning mine. It is not the cheapest thing to drive. Requires 93 Octane, tires are expensive, Mobil 1 oil etc. With that said I would not give mine up. I just like to drive it and feel better driving it. (Hard to explain but the kids like being dropped off at practice etc. in that car) I suppose it is really cool if your a car guy and I am? most folks just think it is a Trailblazer but enthusiast know the difference. Good luck! Just for reference mine is a 2007 1ss and I paid 22375.00 with 20,000 miles on it. I have had it 3 years come April. Feel free to PM me with any questions.
