A proper refurb by a decent company like lepsons will be around £280 ,I have seen a nice straight set on Ebay at £1000 and these have been done by Lepsons , but they have hung around for weeks so imho they arent going to sell for £1k
I think the problem now is there are so many cheap wheels around new
the value of E9X BMW is falling every month so why spend £1000 on wheels and seven or eight hundred on a set off tyres.
You can buy a set with tyres mint from BMW Autosport for £1300 there are also really nice sets on ebay around the same price with make me a offer .
I have a E92 and my wife is always kerbing it so I looked for some spares and now just get the damage wheel refurbished at £90 by lepsons collected and returned with the tyre refitted and balanced
