It looks like MINI may have quietly solved the paint rub issue with new cars:

This looks like MINI's solution to the paint abrasion problem. I wonder if the mat can be retro-fitted. Of course, my mat has a cut-out around the intercooler intake, and I haven't looked at the underside of a Cooper. The surface of the mat is almost like the side-skirts and spoiler material. As I point out at the photos, one should probably make sure that the gasket faces are always clean, so they don't get abrasion. It's some slick engineering.

This is encouraging news for us with the paint rub issue. However I feel like I've seen a couple recent build Coopers that don't have this mat yet. If anyone out there with newer MINIs (MC or MCS) can take a look at the underside of their hood we could try track down when this change happened and how widespread it is. I'm also curious if this is just for the MCS or will eventually make it's way throughout the line.

For more information about the problem read this post and then this follow-up story. Here are more photos of the mat: 1, 2.
