Hey Russ,
You're not the slowest right now... Your car is faster than the Volkswagon powered Cobra I saw last year at the NorCal Kit Car show last year, and definitely faster than than all those unfinished kits sitting out there in people's garages right now.
Don't be too hard on yourself, hey, at least you own one. We are all lucky to be able to own one, I believe. Good Luck.
