Those never went any farther than the drawings there. However, they later inspired tge Razor body that sells today. There were two original designs: F1 style and Grand Prix. I'm unsure if any GPs were sold, but the first 20+ SLRs were F1s. Theres about 5-10 Razors out there. I have the first driving Razor. Take a look at my thread; "ViperJustin SL-Razor Arrived!" for more pics of the Razor.
Edit: If you have any other questions regarding the SLRazor, don't be afraid to ask.
Justin you have the actual razor body right? and then there is the grand prix and the F1? Has the F1 changed at all since the revamp in 2010? does anyone have pics of the pushrod style suspension on the F1?
