The McLaren F1 is an actual race car for the street, low weight, etcetera. The class rules for sports car racing have since changed (with prototypes, rather than homologated "street" cars, in the top class) such that a similar car would no longer be built. There are the Saleen S7 and Mosler MT900 but they're not as powerful.

As for the Veyron, it's a whole lot heavier and while it obviously takes a whole lot of engineering to make any roadgoing vehicle go that fast, it still ain't a race car. Also, one has to wonder if anyone will ever drive the damn things or if they all become instant collector's items.
