[quote=howard MMC chassis are now painted not because its better but because its cheaper.

They spend less time fixing warped galvanising, too.. Price is little different I believe, but it's also more environmentally friendly I was told.
The M3W has had this coating on the chassis since they were introduced, although to be fair, rusting of the chassis isn't high on M3W owners agenda...but they don't peel their coating...unless it's to weld it...
