I have no idea. It completely depends on demand.
This is definately a "lay your balls on the line" project for a small business. If people think the car sucks and I don't sell any, I'm screwed. If I only sell a few and I getmy investment back, then I at least get to break even and drive around in what I think is a cool car.
If I convert 10 cars a year I'll be happy and say the project was worth it.
