John, good point on price - but also note that the 5L is bolt on, no welding with no changes to or removal of the body; the 5L also has quite a few technical advances over the MulFab system. We, PM & I, started from different places and ended up in different places. I started from scratch with calcs to achieve good ride, good handling and high roll stiffness, PM started from a race system that had such different needs. Horses for courses I think. Regards PJB.
