Hey Alemito, I think you will be hard pushed finding a steering wheel from M roadster or coupe. I would suggest having your steering wheel refurbished. Many members on this forum have used the below company with amazing results. I'm sure they'll be able to cater for your individual specifications, i.e. M sport coloured stitching. It's definitely the route I'd take if I was looking at steering wheels.
