You can try E-bay, but very few cars share our specs. Look for 4X108 mm, or 4x4.25" (check my math) with a 40mm offset. Some of the older Audi's and Vw's use the same bolt pattern, but their offsets are different.
I did actually find a set of new wheels on E-bay that would have fit the contour, but they had some design elements I didn't care for, so I didn't get them. Price was good. It took some digging, though, and patience.
Just a thought, if you're trying to save money.
