well i knew i'd regret not going with the gt package. i was wondering if it'd be possible for the dealership to install the factory leather/power/heated seats. if so, approx how much should i be expecting to shell out?

 

No.

On the other hand, you can get *better* (IMHO) leather from Classic Soft Trim (http://www.classicsofttrim.com). You can get colour and texture combinations that the factory stuff can't match, and you don't have the hard plastic backs than can scratch, crack, etc.

For heaters:

...among others.

 

Or you can do what I did and get a leather interior off of Ebay. Got the seats front and rear and the door panels from a wrecked 8. The seats are plug and play, not real hard to install. The door panels really take all the time. I had to purchase the heated seat switches and the panel for the center console from Trussville Mazda. The red and black leather has really transformed my 8. I love it.
