They put out a very impressive product...I guess that's why Carol Shelby bought them out ;-) The overall cost is still a lot more than Factory Five Racing though. I like the idea of an entire pre-packaged kit that you can assemble in your garage (minus the engine & tranny) for between $12K & $13K. The total cost to build one of their kits (base 5.0 mustang powerplant) is under $20K. You just can't beat that.
