You can buy replica CSLs in any finish you like, but the reason I didn't after a lot of advice from the forum and this is what I was told...
You can't be 100% sure of the build quality of all of them, there are a lot of good and a lot of bad. Also they weigh a tonne and seen as tho it is an M car its sacrilege putting replicas on it, as the weight could change the characteristics of the car (handling etc). And the obvious the originals look the balls.
But of corse you can have them resprayed to what ever colour you like, most good companies will take the wheels back to the metal and start again in the finish required. That is what I was going to do, I like the gun metal grey colour on the ones I have and wanted the CSLs to look similar. But these wheels are original paint, never been re-furbed or resprayed and are in incredible condition like brand new. So I was thinking about resale value, would the OEM wheels be worth the same if they had been modified? and would they be as desirable? Then I put them on the car and just thought wow, there is no need. It looks better OEM, and trying to reduce the modified look of my car after some advice from some other forumites.
So the plan is to put them on and live with them for a while and see how I feel in a few months
In that respect I have been looking for 3 months for a set and have only seen 4, 2 of them were in an awful state so I wasn't going to touch them, another pair I couldn't work a deal with the seller and this set I found from a great guy in yorkshire and jumped at them.
So it is quite hard to get hold of a "good set" and i don't want to ruin them, not only for the look of my car but I no I won't own them for ever so don't want to ruin them for the next user.
