We already have a 1997 Jimmy and I personally think its a major peice of shit. Everything about it sucks brakes, engine, transmission, handling, etc. No offense to anybody that might own a Jimmy.
The new Envoy is a completely new vehical. Its only been out a few months.
The engine is a major selling point. Smooth, responsive, very fast for a 6 cyl in a SUV. Its inline 6 cyl has more hp than my 1999 F-150 with the 4.6 V-8. Not sure how the torque compares though. The Envoy is rated to tow 6400 lbs with the 4X4 package.
I'm not sure if the one we picked out has the self leveling suspension or not, I did see it work on another one in the showroom though. Kinda like the air suspension on my Lincoln Mark VIII.
We haven't ironed out the money details but it looks like they aren't doing much discounting on it yet, too new.
I didn't know Chevy also had one, the Trailblazer, I might look there tomorrow.
I'll try to post some pics over the weekend.
For now here's a link to check out:
