you could prob get a custom one made or a universal one made to fit for that. may aswell get the low ones from nengun for that money haha! (good excuse for the mrs) ;)
just about any 4 stud wheel will fit there is only a few companys that use the 4x108 fitment Fords puegots citroens and then the 4x98 fiat alfa fitments about 75% of the others are 4x100 so there is a good selection to choose from :D just remember the spigot rings :D
