Under the front-hinged hood is a Roush Performance 427SR V8 fed by a Holley carburetor and polished Edelbrock intake, sparked by MSD ignition and breathing through tubular headers to side-exit exhausts. Power goes to the rear wheels through a Tremec TKO600 five-speed manual. Recent service in July 2025 included an oil change, new spark plugs, and fresh transmission and differential fluids. A brake-fluid flush was completed in preparation for the sale.

The fiberglass body features a single roll hoop, hood scoop, Talbot Berlin-style side mirror, quick-jack bumperettes, fender vents, and a LeMans-style fuel filler. Paint-protection film covers the front end and rocker panels. Rolling stock consists of 15-inch Halibrand-style wheels with safety-wired three-eared knockoffs on Cooper Cobra Radial G/T tires, with braking handled by four-wheel discs.

“The app was a lifesaver today at the DMV. When they had our company name recorded incorrectly, I was able to immediately pull up the scanned registration document, show them the correct information, and get the issue resolved on the spot.”
David A.

“The app saved me a ton of frustration today. I called the service center, and they asked for my VIN. The car wasn't even at my location, and just as I started to stress, I remembered I had the VIN stored right in the app. Problem solved immediately.”
Tom R.

“I wanted to show a potential buyer photos of one of my cars spur of the moment, but found myself scrolling endlessly through my camera roll. Then I remembered the app had all my car photos organized and easy to find. Within seconds, I pulled them up and even shared a direct gallery link with the buyer.”
