These cars are not exactly what you'd call slippery (Esp. the VW), in fact
they are really rather blocky, in addition the honda suffers from being
grossly underengined.


My '70 Opel GT (esentially a Kadett in a diffrent suit) got marginally better
milage at 70 than running slower (28@70 vs 25@60).  The engine/trany/rear-end
ratios were such that the engine ran at 3500 RPM (MAX torque) @ 70 MPH. The
body was esentially the same as the (69?-82?) Vette (actually it's
the other way around Opel had the body style first).
