Just wondering when you get new aftermarket wheels/rims/tires, what do you do with the orignal ones that came with the car? Browsing through these forums, it doesn't seem like there's a big market for swapping/selling. I don't really have storage and I'm wondering how to sell them.
If you have a Five and you are selling the OE 17" wheels they should go quick if you price them right. I would have bought a set rather than my CT wheels if they were not so expensive. Most people price them at $1000+. Try posting them for sale on this forum and Craigslist? eBay is another option.
Use them for your snow tires, you do not want wide snow tires anyway. (Should you live where it does not snow and wonder why we advised this, telling us your Location always helps our advice)
