Nope,
None of the Contour mods work on the Mystique. Something about the Mercury badge
Just kidding, there are all sorts of mods.
I'd say start with the main page at contour.org and look at some of the information already posted about modifications. I do believe costs are posted on many as well.
http://www.contour.org/mods/ Then, come back with a specific question, such as, those of you who did the XYZ mod, did it work for you?, would you do it again?, and so forth.
FWIW, I'm a performance kinda guy and hardly find time to wash my car, so appearance mods are not important to me. But go fast, stop fast and turn fast are.
So the first things I've purchased are wheels and tires, and new brakes. Koni's and Eibachs as well as the AussieBar (an anti-roll bar designed by one of our members) are my next suspension mod. I've also installed a Borla Exhaust.
When all of that is done, then maybe I'll spend the $$$ to get my ride made pretty
Heck, I usually listen to AM radio, so I'm not dumping any $$$ into booming beats.
I'm not cool either
but that is another story from the off topic boards. But it does help explain why I really don't care about the show aspect of my car.
HTH,
TB
