We have owned this '08 Wrangler for 4 months now and totally love it. Reviewers keep harping on lack of acceleration. I have no problems with the V6. It is very sufficient. If you want sports-car acceleration, you should buy a sports car. For God's sake, this is a SUV. It wasn't designed for extreme acceleration. It truly does everything in an extremely FUN way. You need to test drive one to understand.
Favorite features are the MY-GIG and the 18" alloy wheels. A friend loved my Wrangler so much he ordered one for himself!
I've been driving this Jeep daily for 4 months and the only thing I can suggest for improvements is to offer heated seats!
