Same basic frame on Buick, Saturn and GMC. No V-8 for any in '08. All built in Lansing Michigan and known as the "Lambda". Buick is slightly different with portholes and thicker glass and soundproofing (supposedly) as well as a 4 year warranty (others are 3/36). My Outlook is real quiet.
Big news is that Chevy enters the game with the Chevy Traverse in Jan/Feb 08 which will be another Lambda (no v-8 here either).
I must say I am totally happy with this car, and I know FWD may be a turn off for some, but I am in flat Florida it works fine for me, the V-6 has 275 bhp. It has a power liftgate, 19" rims, remote start, and more interior room than a Tahoe in a considerable more stylish vehicle IMHO. I actually came out of a Lexus and was not in the market at all for a GM and this truck won me over on first sight.
BTW what is DP tire gel?
Thanks for the positive comments!! I busted my butt on that job.
