I already have the street black one with flames (S&H set), and I quite like the new guide system.
My paint finishes are not as good as scalextric's, and it seems that any project like that ends up with a sky-rocketting project, so I only do ones I really want !
As well as the paint finish, there is the wheels, and the exhausts (the street version should have exhausts out the back - the body even has the arches for them)
Also I can't see in the pics a chrome bumper, although it may be there. But there are no chrome bits on the grill like in the picture.
I think its kind of ok, but not good enough or different enough to tempt me into buying a 3rd corvette (the one in the pic would have had my money)
