I think that any sort of factory supported motorsport programme for the Crossfire would raise its profile and lend some credibility, assuming it is relatively successful; if it was getting beaten by everything then maybe it would just reinforce people's general opinion that its not fast enough!

The aftermarket is generally governed by the popularity of the car - very few companies pump resources into producing stuff for a car that is unpopular. When I bought my Crossfire it had only just been released so I didn't expect any aftermarket activity anyway.
The exception to this is where a manufacturer announces a model and has a race series already lined up for it, like the many one-make championships, Renault Clio Cup etc.

Personally, even though I am a complete car and motorsport nut, the lack of such sporting heritage didn't affect my opinion to buy. I have an old 911 to satisfy that. I wasn't actually looking to buy a new car but I just wanted one as soon as I saw the concept car. I then saw Tiff Needell reviewing the production version on 5th Gear (quite a balanced review as it turned out) and his parting shot was that "In the UK it may have limited appeal, but for some THAT will be the appeal." and for me that is the case, and I also liked the fact that it was engineered by MB. I could have had a Lotus, 350Z or TT etc, but everyone and his dog has one of those and I when they came out I didn't suddenly want to buy one.

As it turns out I am more than happy with the Crossfire's performance as my daily transport, and happy to take it to that track as well. That's not to say I don't think of trying to improve it!
