Nice to see you EDITED your comments.
As you should know, tuners have much less to deal with than manufacturers. A tuner can make a product that only a few people would want and they don't have to deal with those pesky governmental regulations. A manufacturer needs to make a product where many more people would actually plunk down the cash...besides the emissions controls, crash testing, etc...
And the Veyron not having a racing history? How many cars have a racing history before ONE is produced?
