The other option, which is the road I took, is to buy a brand new set of after market wheels. You can get a good set for abou £300 plus tyres, which is cheaper than replacing your smart ones with new, and you can choose a style you like and make your car a little unique.
You can then sell yours on to someone who wants to refurb them and make some ££ back.
Cheapest though is as stated, to get them returned yourself and coated in your choice of colour.
Incidentally if you look at the bottom of the forum list you'll see a marketplace section, where people will list their wheels and other parts they're selling.
