did a quick google search, no joy.
Any ideas?
For what vehicle? 1956 Ferrarri ..dunno.... but for everything else try Ebay.
I've always found one on Ebay for last four cars (Saabs, Toyota Yaris) no probs.
I'd go with eBay too.
Got a decent second-hand skinny spare for a 2005 Ford Focus quickly and cheaply a few years back.
I put a Wanted add on my local Gumtree and got a reply from a surprisingly close seller. Picked up the wheel for cash and very happy!
I bought a set of 4 alloys from a breakers yard .... advertised on ebay! (winter tyre requirement)
