Thats a lot of info. Let me see what I can do for ya.
As for the fog lights you can search around junkyards to get the cheapest set
Search Copart Finder Or you can go with some PIA 510, these fit nicely in the SVT socket and im sure will also fit in your socket. These are fairly nice lights and can get expensive. There is a groupbuy on them that ends tonight actually if you go to the groub buy section you can find the ordering information.
As for spoilers I dont really like them

. You can also check your junk yards. If you want a stock one a couple companys carry OEM replacements and there are a few other places that carry touring wing styles. Check some of the links on the front page.
As for wheels if you really like the SVT set you can usually pick some up off ebay for around 500 used. You can get them brand new from
Tirerack for $150 a piece. They have terrific customer service and fast cheap shipping. They also have a virtual wheel fitment guide that will help you find some wheels and you can even view them on your Contour. I highly recomend checking there site.
As for the ground effects your going to have to get the SE or the SVT from a dealer. I would try a man named Bill Jenkins.

If you have the Ford part # already, Check my inventory!!
He has great prices on all Ford parts and offers a discount to CEG members. He could also get you the fog lights, spoiler and wheels. But they will be generally more expensive.
Hope this helps a little if not try a
SEARCH .
