If you are looking into getting a new one at a good price, CamaroScotty who works at a dealer in Cedarburg PM'd me regarding the deals they are giving right now.
He priced out two TBSS's for me.
The first one was a 2WD 1SS Trailblazer with cloth seating for about 25k brand new.
The 2nd one was a AWD 2SS TrailBlazer with leather seating for about 28k brand new.
Including current incentives, and GMS pricing. He also gave it with GM Supplier discount if you don't get the GM employee discount...
Definitely send him a PM...
I'm currently talking to a dealer way the hell out on the West Coast because they have a have an 07 AWD TBSS with leather sun and sound package, with under 10k miles and are asking for like 21k...
Good luck though, and check out
www.tbssowners.com. I got alot of useful info from there...
