I've seen those and he wants 350 for them..... to be honest I wouldn't pay that for them unless they were mint MK1 campaign wheels with center caps.. I'm guessing these are later mk2 ones as he states mk1/mk2 p-slots.
However, thats me and what I would want.
They are freshly powder coated, diamond cut and lacquered and it sounds like they are in as new condition so seems a fair price with tyres.
