A few thoughts on the SBR- I'm pretty sure the 4 in SBR4 means 4-cyl, not "comfirtably seats 4". First of all, why wouldn't there be an ingame 6-cyl model? Also, the eSBR can seat 4 comfortably, but it doesn't have a 4-cylinder engine, does it? I'm thinking that it might have had a convertible CR4 or SR4 variant until maybe the 80s, and could have even had a weird targa model. An SBR6 would be cool, and would have provided a base for a silhouette racer of sorts.
