this is a tough one to stay out of, I have had my CAV for 2 years and the car has held up really well. It is a great design and the build quality is excellent. I have also worked on Roy Sayles new CAV demonstrator, many improvements, dropped floor, Gurney bubble, way better seats, Wilwood brakes and Smith's gauges and a host of improvements like beefier front and rear uprights, fully adjustable suspension, better pedals, on and on. If you want to drive soon and spend your time and money on perfecting the driveline(and not have to build an entire car) a turn key minus is hard to beat. IMHO
