I am trying to keep an unofficial "registry" of Hi-Tech cars and ran across this one for sale last week. I know nothing about it except that it has the HTR VIN you are looking for:
Shelby COBRA 427 SC Roadster 1965 Silver For Sale. HTR65SC0023 SHELBY COBRA 427SC REPLICA - HI-TECH MOTORSPORTS, SILVER, 351C
I would absolutely not rule out the car that Jeff is referring to - it is awesome. A late HTM car that is built very much like the originals.
