When father and son, classic car collectors John and Hayden Groendyke, who specialize in collecting an assortment of Auburn, Cord, and Duesenberg Classics, were bitten by the Hot Rod bug a few years ago, the result was this stunning Marmon V16 fenderless low-boy roadster.

Hayden was never really interested at first in building this custom roadster. However, when he contacted his father’s pal, Richard Atwell for some rare 1931 Marmon parts and found out that they were available, he had this impetus to give it a try.

The Groendykes made sure that their restoration project will only make use of an authentic V16 engine. Marmon built only 390 V16 chassis between 1931 and 1933. The heart was obviously the engine. The very first production V16 in the world, the long-stroke Marmon has a 3.125” bore and 4.0” stroke for a displacement of 491 cubic inches. The aluminum block and cylinder heads were decades ahead of their time. With a single Stromberg DDR- 3 carburetor, this behemoth was rated with 200hp at 3,400 rpm and 400 ft/lbs of torque.

Groendyke’s own shop did most of the mechanical work and put the Marmon together once the bodywork, paint and interior bits had been finished. It was finished just in time for its debut at the 2011 Grand National Roadster Show. Stunning as it is, it was not able to bag the title of being America’s Most Beautiful Roadster. However, it managed to turn heads and created enough buzz than can rival any other winning cars in the said competition. Since then, the custom-built Marmon hotrod has never been shown. It’s been stored in the Groendyke’s climate-controlled museum, and only driven five times for short distances. The classic hotrod is now on auction at Barret-Jacksons.
