I had a '95 M3 with cloth seats option. Alcantara bolsters and motorsport cloth inserts....Alcantara was light/medium grey. It held up better than leather.
I had the car for 11 years. It went to more track days than I can count and spent a lot of time in dusty, dirty areas. I wasn't always sparkly clean on the 300+ mile drives home either. All I ever had to do was brush it off with a cloth or brush. Seriously, it never wore and it never stained. I ate snacks in the car too...nothing. I did use Scotchguard on the seats the first week I got the car. Never re-applied. Parked it in the garage with windows down. I used to flip the back seats down and put tires in there. There were tire marks on the plastic backs of the seats, but they cleaned up to about 95% too. I sold the car at a great price with a lot of goodies on it. It had really been driven hard. New owner had a few problems, but got it up to snuff and, I'm sure, had as much fun with it as I did. It looked near new when I sold it.
Alcantara rocks, but I don't like it on steering wheels or shifters...if it's my car. If it's someone else's, heck, I love it!
