I think there is only a limited market for each individual years championship DVD's, but if there were three compilation DVD's with the best of the 70's 80's and 90's, they could be targeted at a much wider audience. I think there would be a great demand for these.
There are two DVD's available in the MVC catalogue, they are just listed as Rallycross Review 1994 & Rallycross Review 1995. I dosn't say anything about them, I don't know wether they are European or British. I have ordered the 95 one, so when I get it, I will do a review.
