The first and best piece on a non-PP Mk7 was by George Karcher in recent CAR mag. It's a bit misleading of VW & the press to make all these comparisons between PP & standard cars. The only thing to settle it would be a real road (non-track) back to back test between a PP and standard with otherwise identical spec.Karcher was mightily impressed with the non-PP car, that's all.
EDIT:Inevitably this means virtually all car comparisons are of a subjective nature which we are all well aware of, so perhaps I'm being too keen here and should just let them get on with giving their opinion and then treat it as just that!
