Dont get sucked into "the body/chassis from" prices. These are quite a complex kit and something as simple a door or front suspension fit will normally be associated with a door fitting kit or a suspension fitting kit, It just goes on and on. My advice would be to join the cobra forum and plug them as they will be more aware of the rip offs and pitfalls. They are basically a road legal dragster and poser wagon. I miss the one I had <500hp>

but thinking back to the times when fuel was a lot cheaper I once got through a gallon of squirt in less than a mile

I only know that because I was having a tinker and it ran out of fuel so I tipped a gallon in and never made it to the garage a mile away. Mind it was fun
