I was originally looking at the M-Sports as well. The only thing that I was worried about was the weight. I had called ADR and they said the 17s were like ~20lbs. I am not positivie on that number because they guy sounded like an idiot but that I am sure is part of the reason BBS are so expensive. They are much lighter. Just my $0.02. They definately look awesome in black or in silver. Good luck with your decision.
