Easy now, and sfy is just saying what TEST DRIVE has been since it's inception, all about supercars and driving them really fast.
Todays kids want a lot of stupid cars in games because they watch them in certain cartoons and think they are great as they do one thing and one thing only. However pure classics like those you mentioned definitely deserve a place in a game like this as even the richest of the rich would probably love to have a mint Mercedes 190E, Escort Cosworth, Audi Quattro, Mini Cooper, BMW M5 E34, BMW M3 E30, BMW M1 Procar, Lancia Delta Integrale, Lancia Stratos and of course many US classics too. The odd icon from Japan would be good too like the original Skyline upto the new GT-R and of course the legendary NSX and even a Supra. Other than that though the cars only dreams are made of is what makes TEST DRIVE great and if Bugatti are in I really hope we get the EB110 and oh praise be to Eden give us a Dauer 962 LM!!
As Churchill once said: Oh yeeeeeeeeeessss!
I've read something about a Devon GTX somewhere in the past also, that car looks mental!
