P6 was a lovely car to drive and imo a good looker too[I had one]but strictly a 4 seater really.Front suspension used springs mounted horizontally to the bulkhead[they say it was done this way as they were toying with the idea of slotting a turbine engine into it]don't know who designed it though.SD1 was again a lovely car to drive and looked well[let down of course by BL's legendary build quality and the fact that in the paint plant where they were painted-with a then new fangled paint type-had the extractor fans fitted wrong way round so they pushed air into the place rather than pulling the air out!] I had 2 of those though sadly not a Vitesse version.Designed by David Bache I believe? Who they say took frontal styling cues from the Ferrari Daytona.
