Tony do you have any pictures of your work to enthuse the masses?
What sort of money are you looking at for a full space frame car (super open ended question i know :))?
Yes it is an open ended question. It depends on what you want included? Wiring, dash, data lgging, air jacks etc all vary the price. Also depends on what power you are looking at which affects the transmission, axles etc. If you go big power then you will spend big on these items.
At the end of the day it depends on what you want to achieve with the car, a state level car can be built a lot cheaper than if you want a shot at the national championship. What did you have in mind?
