Do MV3 suffer cracking? I though cracking was only a significant issue on the 19" MV4??
Anyway, I bought rep MV3 for winters from wheelworx.net for £300 for four a couple of years ago.
Despite my concerns about paint finish they have lasted 3 winters without a mark (where the factory wheels were bubbling at the centre bore after the first winter) and the paint finish is a nicer brighter silver than the BMW MV3.
Also, when I asked there was no insurance cost as they are the same size / style as originals, but of course this may be insurance company dependant.
E63 AMG here at last!
