The whole vehicle came only due to the fact that I was bored one day with the 4993 Main model (the convertible) so I decided to experiment with new vehicle shapes.
It kind of reminded me of the Super Street Sensation, same chassis, different body. I chose to do this because the existing chassis was already a good starting point, so why change it and start from scratch?
I see elements of both Elfin and Caterham, but I just built what came to me. But hey, with only using the parts from the 4993 set, I think it looks damn good.
Not the easiest set to build good alternatives with, but I agree that this looks pretty cool! Good choice to re-use part of the chassis and it was nice that you were able to stick with exclusively 4993 parts. Perhaps you'd like to add this to the group "Alternate designs of a Creator" as well...
