Hi,
I am interested and researching about building or having one built GTM as a daily driver in California. Besides emissions which I believe now is fixed with Chevy E ROD engines, what are the other obstacles of building a car to register in California?

What is the build cost of a new STOCK Chevy E ROD LS3 engine GTM car without any extra aftermarket parts? I'm trying to figure out complete build cost versus using used donor parts.

Has anyone calculated MPG...just out of curiosity for a light car with LS3 engine?

Thank you!!!
