Frank,wherever I said that is gonna come from a comment Hucho said,regarding Walter E.Lays research in 1933.
Lay did a bunch of scale model car wind-tunnel studies,got about five of 'em down to Cd 0.12 with full boat tails.
He found,as did Fachsenfeld and Kamm,that if the fore-body had crappy flow,the boat tail was a moot point,as flow would be un-attached coming to it,rendering it useless.
Hucho goes on to say that virtually all production cars circa 1986 and later will be clean enough to ignore fore-body streamlining and to basically concentrate on the back end.
