The Herb/Matt Adams cobras have a "backbone" frame which derives it tortional rigidity from the transmission tunnel design. This translates into a little less room in the cockpit. The genesis of this design is gone over in Herbs' book "Chassis Engineering":

The bodies were by a fabricator in Tempe, AZ (fellow named Kube if I remember right) and to my eye were very nice (as in accurate).
The suspension design is as good as anything out there in my opinion.
Matt ran at Run-n-Gun when it was held at Mid Ohio and was one of the fastest on the road course and autocross. Engine was very mild and only ran in the 13's on the drag strip.
He also ran a customers VSE Daytona coupe at Run-n-Gun at Gateway Int'l and again did very well This was a number of years ago.
Bit of trivia....the Cobra that spins out at the end of the movie "Bad Boys" is a VSE Cobra. They had 2 for the filming, one was a trailer queen, but for the high speed spin they used a VSE. (You can tell by the "VSE" on the brake hat.)
With regards to resale I would not expect it to hold up as well as a Superformance because it is going to appeal to a smaller crowd. Also build quality will make a big difference (variability).
