Story & Photos by Martyn L. Schorr

Intro: I was just a car-crazed lad when I saw my first Baldwin-Motion Phase III Corvette on the cover of CARS Magazine. The bright yellow machine had ‘67 side pipes, the Baldwin-Motion signature-style ‘67 big-block Corvette hood scoop on top of the ‘68 big-block hood dome, a GTO hood-mounted tach, flares on the wheel openings, and deep-dish Cragar mags. WOW! What’a sight! Joel Rosen made sure the cars had a heap’n help’n of red meat, and Marty Schorr, CARS editor and Motion coconspirator, made sure there was plenty of sizzle!

Baldwin-Motion cars went on to delight Chevy lovers for years and quickly became legends. In ‘69, Rosen turned the Phase III Corvette into the Baldwin-Motion Phase III GT – the most expensive of all of the Baldwin-Motion cars. After specialty cars roll (or peel out) out the door, many live hard, hard lives, with less than happy endings. But then some become cherished members of their owners’ families. This is the story of a much-loved and enjoyed Phase III GT Corvette.

The Dr. Henry Rollings Baldwin-Motion 1971 Phase-III GT C3 Corvette’s beginning

 Many of Duntov’s mule Corvettes were white – so were most of Bill Jenkins’ race cars and Jim Hall’s Chaparrels. Sano white was Dr. Rollings’ colour choice for his personal Grand Touring Corvette.

Purchased from the original owner’s family in 2008, Adam Tuckman’s 1971 Baldwin-Motion Phase III GT Corvette is the last built, highest-optioned, and most original known. Between 1969 and 1971, Joel Rosen produced just 12 GTs.

On June 3, 1971, Dr. Henry Rollings took delivery of his air-conditioned, 500+ horsepower, 1971 Phase III GT from Joel Rosen at Motion Performance in Baldwin, New York. Power was supplied by a blueprinted and balanced 454 LS6 big block built to LS7 specifications and fitted with a GM high-performance hydraulic cam, open-chamber L88/ZL1 aluminum heads, headers, and a Holley four-barrel.

Backing up the potent Phase III engine: A massaged M40 Turbo Hydramatic, Hone overdrive, and a 4.88 Posi rear. Creature comforts include a custom button-tufted interior and stereo system, and numerous power options from the factory. Thanks to the fastback rear window, there’s a storage area for luggage behind the bucket seats.

Phase III GT Corvettes for export out of the US had very cool-looking Lexan headlight covers that were illegal here in the States. Dr. Rollings GT was 100% street legal, sans the headlight covers.

Dr. Rollings paid his bill ($16,283.00), hopped into the GT’s plush interior, and drove home to Savannah, GA! ($133,000 in 2025 dollars!) 

Between 1971 and 1989, the colourful cardiologist who owned and piloted vintage World War II aircraft used his Phase III GT for making house calls (imagine your doctor pulling up for a house call in this beast!), towing his Jaguar E-Type SCCA racecars and high-speed touring. He put more than 31,000 trouble-free
miles on his unique Corvette Supercar. In 1989, he gifted his GT to his daughter and son-in-law, Ellen and Don Glasser. Dr. Rollings passed away in 2003.

GT (Grand Touring) machines were originally designed for a “grand tour” or a big, long trip. Arguably, the most significant design flaw of the ’68 to ’77 Corvettes was the coupe roof. To open up the back storage area, Rosen’s GT Corvettes featured a unique fastback rear window that provided enough room for two suitcases. Duntov said, Joel, you were able to do what I wasn’t.”

“Dr. Rollings owned imported exotics, raced sports cars, and flew restored Warbirds. Once he took a test ride in a 1970 GT that we had just finished for a customer, he was hooked,” said Joel “Mr. Motion” Rosen. Documented by Joel Rosen for the Glassers in 2003 and again for Adam Tuckman in 2008, it is the last built and most highly optioned Phase III GT. Other than being repainted in the 1980s, it is the most original GT known.

Now here’s a Corvette interior you can live with. Plenty of room for groceries, golf clubs, or two suitcases. ROAD TRIP! The device between the seats is an 8-track Tape Player. The storage bins accessible in the floor of the storage area were for 8-tracks such as “Tom Jones Greatest Hits”, Three Dog Night, and The Partridge Family!

Dr. Rollings’ GT has been restored to exactly how Motion built it in 1971

Rosen’s yellow Phase III GT is now owned by Dan McMichael. Gary “The Local Brush” Kupfer originally striped and trimmed Dr. Rollings’ GT in 1971, and applied the finishing touches (black Phase III stripes) to the GT in 2010. Its public debut will be at the Muscle Car & Corvette Nationals in Chicago, IL., on November 20-21, 2010. – Martyn L. Schorr

At the end of the day, “beauty” will only get you so far in the world of high-performance cars. Ultimately, it’s about “what’s under the hood!” So, feast your eyes on these specs…

I’m certain that Corvette and Chevy lovers will be talking about Baldwin-Motion cars for many, many years to come. The Motion Performance cars were forged in a time when life really was simpler, though it didn’t seem that way at the time.

For those of you who might not know who Marty Schorr is, you should know this. While editor of Hi-Performance CARS magazine, Marty teamed up with Motion Performance owner, Joel Rosen, to build Chevrolet Supercars. Marty developed the branding, advertisements, catalogs, and editorials covering their Baldwin-Motion Chevrolets. Joel spun the wrenches, and Marty spun the spin.

As editor of CARS magazine, Marty gave the Baldwin-Motion Phase III Supercars tons of attention. Fully-restored, genuine Baldwin-Motion Supercars are today some of the most valuable collector cars on the market. Marty also launched VETTE Quarterly in 1976. The magazine eventually became a monthly publication, as VETTE Magazine, and was in continuous print until the January 2020 issue. 

Dr. Rollings $16K Corvette was over three times as much as a new stock 1971 C3 Corvette. If and when other significant Baldwin-Motion Corvettes surface, we’ll be sure to post updates here! – Scott
