I'm not 100% sure, but I believe that there is more than the E1A finished in the E-Series.They said that Paul had the P5 flat out on the track one day. They didn't say how fast he had it up to. They said Rouch has had the car for some testing. I think they had the E1A. Continental has also been working on the brakes.
E1C is going to be the new touring/marketing Elio; so that could mean that the B, D and maybe a couple more (?) are further along than when we last saw them.
