"The engine is a 750cc Renault. I am driving in the photos which were taken during  practice sesssions in 1967. The car was a one off built by Pierre Ferry. It had a tube frame, full envelope aluminum body including belly pan, 40 gallon fuel tank with filler under the headrest, a five speed "crash" box with selecter on the driver's left, extremely comfortable cushioned leather seats on aluminum frames, removable aluminum tonneau with Dzus fasteners, leather hood straps, rear panels to cover the wheels and a remarkably roomy cockpit. (I am 6'4" and drove the car comfortably without modifications) A roll bar was installed under the headrest. It's competition in Europe included OSCA, Stanguellini and Moretti."

From Website Visitor "JP":

"Pierre Ferry built many special Renault Powered cars. a Ferry repared Dauphine won its class in the Mille. I think 1955?  I want to tell a little about the Ferry Renault Jack Reynolds owned. It was never cut up into a dune buggy, the car is very much alive. It was found it in a junk yard about 6-7 years ago, in Riverside county. The car sitting on a pallet. It was also featured in a 1958 issue of  Road & Track, next to a Ferrari.  Last I heard the car is being restored somewhere in California.

Car was so fast in its day, the SCCA officials demanded a engine teardown, when it was outrunning D-types and Ferrari's in the late 1950s.  It won at Paramount Ranch, and its class at the "L.A. Times Grand Prix" at Riverside in 1959 (?)."
