Andy, you state:
"The beauty of this car is that it is fully road legal and you can drive it to the track!"
Hardly revolutionary given the plethora of road legal track biased lightweights available at similar or less money.
Lotus/Westfield/Ariel/Caterham/Radical/Brooke/Grinnall/Toniq.
Not forgetting that your pricing isn't too far shy of a base model Boxster.
I have enormous admiration for anyone brave enough to follow their passion and produce a vehicle from scratch but fundamental analysis shows that desireable aesthetics often triumph over dynamic capabilities. Marry the two, market your product correctly and you're on to a winner.
Sack the stylist, restyle the bodywork and you may just pull it off. Guffaw at this suggestion and you'll sink.
I wish you very well.
Paul.
