Stupidly expensive. One thing I've never understood which someone on here may be able to clear up. The CSR has inboard front suspension and independent rear suspension - obviously solving the limitations of the standard set up and should be much superior. So why is the CSR aimed as a road car rather than track? Surely all that stuff would also be preferable on track?
Other thing which is at odds is that it gets the aerodynamics for high speed track work which is totally useless at legal speeds.
