1974 Kelmark GT 1 Mark III
1 of 10 Built - Only Known One Left!
Well documented and built American supercar representing an important era in the seventies American hot rod industry. The KELMARK GT 1 MK III is a purpose built tube framed 2500lb car, one piece fiberglass body and an offset mid mounted 400+ hp 327ci and IRS trans axle.
According to the Kelmark registry this is the only remaining 1974 Kelmark GT 1 Mark III. This was the tenth built by Kelmark Engineering, Inc. This Kelmark GT 1 MARK III was discovered after being stored for more than 20 years by the manufactures representative and underwent a complete professional restoration/update.
There is less than 20K original miles on the car in total less than 100 miles on recent $70,000 restoration.
This particular Kelmark GT 1 MK III was one of the last ones produced by Kelmark Engineering before they were sold to Molded Plastic Industries. The body was specially manufactured with twice the thickness of any other they ever produced. This car has a specially built frame that incorporated a roll bar and integral dual fuel tanks.
A pinnacle super car in the seventies and would be a worthwhile addition to any collection. The styling was inspired by the Ferrari 206 Dino GT, combining the lines of the Dino with the Astro II XP-880 Mid Engine 1968 Corvette concept car.
The Kelmark garnered much positive attention. Car & Driver Magazine, May 1978 said "Fastest documented speed ever attained by a street machine". In a 1977 Car Craft Magazine: "Undoubtedly the closest thing to a street driven Can Am car on the road today."
The Kelmark GT compared to the Ferrari Dino, weighed less, had twice the HP, cost twice as much at over $20k and is considerably more unique as all were custom built. Includes some excellent features such as DOT rated Roll-up Driver and passenger glass side windows with DOT rated windshield and rear window; "Gurney Built" Carbon/Kevlar Seats developed by All American Racers from the 1993 Toyota GTP Car driven by JUAN MANUEL FANGIO II.
They are adjustable and removable built to fit a driver over 6ft tall with helmet under 220lbs. Has the coveted SPCNS California smog exempt title and "RARE RCR" custom license plates available to California buyers.
