Hey Scottrocket, welcome, and congratZ on the 07 base. Looking great. Check out the car care forum too. Lots of useful tips. Enjoy!!

 

Many end up putting in a posi or differential locking rear end on the base. Throw in cruise control and you wonder why you didn't get the Enthusiast. Answer: Normally money, although I've heard a hundred different rationalizations.
I think you are looking between $1000 and $1200 for the installed new rear end. Others may get it more specific.

 

 

Thanks for the tip on the car care forum, i'll definitely check that out. I will probably have to wait until next spring/summer until I do anything to the car because of money but i will definitely be looking into some stuff. 3 things I want right now are to upgrade the stock stereo, put on borla dual exhaust, and probably do the posi or somethin, i'll have to look into that a lot more before i figure out what to do there because that is something i don't have much experience with.
