I also suggest that you take a look at CAV. I am one of their reps, and I think you will be impressed with the quality of the materials and workmanship. We only offer turnkey minus or completed vehicles. The price is very competitive. Our only chassis option is a stainless steel monocoque. I think you will find that it is difficult to build any of the top of the line kits cheaper then you can buy our turnkey minus car. We have several cars available throughout the country for test drives, etc.
