He doesn't even have to go THAT far to find cool wheels with custom drilling. Like Stazi said, because of the popularity of the Focus, older Audi's, some Volvo's, and the Couger... the Contour has a seemingly endless supply of wheels ranging from 14"s to 20"s. Sell your 4 useless sets of rims and tires and buy a set that fits.
You could also swap the hubs out for some from a Jag X-type, as I believe that is a 5x100 lug pattern. Not sure what that will do with the offset, and you'll need the calipers, rotors, etc. Buuuuuuut, it will cost you a TON, no no.. A
TON to do this conversion and will also include you buying some lube to give to the delaership to give it to you while you hand over your credit card.

Probably twice the cost of a set of Awesome 18" Millie Miglia F20's with tires. (1700 bucks)
Just a heads up, as I've already looked into this in the past.
