Your description is quite good, but you don't have to build the entire
car like this.  As previously mentioned, the Corvette's design led to
low radar image even though it had not been designed that way.

You need only bounce the radar from items that would return a radar
image of sufficient strength to be useful.  Generally, this means the
engine block.

Why not put angled plates around the engine that would either reflect
the radar up or down (or both)?  Make the car body out of some
non-radar-reflecting substance (such as plastic).  The car itself
would be invisible to the radar, and the big target (the engine) would
be protected.

Your car wouldn't even have to look "fast".
