The Motion Performance Experience – Part II

Published on by Scott

An Intimate Conversation With Martyn “Marty” L. Schorr and Joel “Mr. Motion” Rosen – Co-Founders of the Baldwin-Motion Supercars
Dateline: 8.10.17 / Photos:  Martyn L. Schorr & K. Scott Teeters’ Baldwin Motion Magazine Archives, Mecum Auctions, Dan McMichaels, & Google Maps – Part one of my 2013 Far Out Radio conversation with Marty Schorr and Joel Rosen is in the July 2017 issue of Vette Vues can be enjoyed HERE. The year 2017 marks the 50th Anniversary of the Baldwin Motion Experience. Before we get into the rest of my 2013 conversation with Marty and Joel I’d like to share an anecdotal story about setting up the interview.

I have known Marty Schorr since 1976, just after he started “VETTE Quarterly”, the first Corvette-only, newsstand publication. I’ve had numerous conversations with Joel since around 2000 and always found him to be polite, but very reserved. When I asked Marty if he’s like to me on my radio program he said, “Sure, I’d be happy to.” When I asked Joel, he said, “Well, okay, but I don’t really have that much to say. How long is the interview?” I told him I did a one-hour show and without the commercials and bumper music, we have around 45 minutes to talk. He said, “Oh… I really don’t have that much to say, Scott. Really.” So, I assured him that if he ran out of things to say, Marty would fill in the rest. When the show started, Joel was reserved, as usual, but quickly loosen up. Before I knew it, he was seriously bench racing! As the host of the show I carefully watch the clock. When I said, “Well guys, we’re just about out of time, Joel said, “What! We just got started!” That’s just what happens when car guys get to bench racing.

Dr. Rollings’ 1971 Phase III GT Corvette “The Most Expensive of All the Motion Corvettes”

Published on by Scott

Baldwin Motion Phase III GT Corvette Survivor!!!

ICS_II_No-204-1971-Rollings-Phase-III-GT-TNDate: 5.2.14 – Time has been kind to the Baldwin Motion Supercars. Today, complete and restored Motion cars are very valuable. Yenko cars have the pedigree of being COPO cars, but unlike the Phase III cars, they could not be personalized. Enter Joel Rosen, Marty Schorr, and the Baldwin Motion experience.

Rosen was the owner of Motion Performance in Baldwin, New York and Schorr was the editor of CARS Magazine (and founder of VETTE). The young men conceived of offering custom-built supercars through local dealer, Baldwin Chevrolet. Rosen knew how to build a Chevy muscle car into a dependable, supercar, with performance over-and-above the factory level. Joel spun the wrenches and Marty spun the spin. Schorr kept the sizzle hot with CARS Magazine “special road tests,” in-your-face ads, special features, and catalogs. A Motion supercar was guaranteed to run the quarter-mile in 11.5-seconds with a qualified driver. When a customer took delivery of their Phase III supercar, they were driving a custom-made supercar. It was all very heady stuff.

Rosen’s higher vision was to offer an American GT machine based on the big-block Corvette. Joel started with his basic 500-plus horsepower Phase III Corvette and added custom bodywork that included a fastback rear window that opened up the rear cargo area of the C3 Corvette. The car was christened the “Phase III GT.” A “regular” Phase III Corvette was already a beast, but if you wanted the next level, the Phase III GT offered all the performance hardware, plus unique, head-turning custom bodywork. The Phase III GT Corvette was Rosen’s vision of the ultimate Motion car for customers with deep pockets. Rosen expected to produce 10-to-12 Phase III GT Corvettes a year, but only made 12 cars from ‘69 to ‘71.

A Salute to the AWESOME, highly collectible, Baldwin Motion Corvettes

In November 2011 there were a few automotive bomb shells dropped on the MCACN Muscle Car Show. Namely three unique Baldwin Motion Corvettes. One Survivor Phase III 454 Corvette, one restored Motion Mako Shark Corvette, and one garage/barn find Corvette, the ‘76 Can-Am Spyder.

The survivor car is known as the “Ankenbauer Phase III 454 Corvette. The car is currently owned by Dave Belk and is just an amazing Motion survivor car. I have a feature story on this Motion Phase III 454 Corvette coming out in Vette Vues Magazine in a few weeks. After publication, I’ll post the story here. The car is jaw-dropping and the owner’s story rocks!

Dan McMichael is a collector of Motion Corvettes. His latest finished Motion car is the 1970 Motion Maco Shark Corvette. There are many configurations of the Mako design. Both Silva and Motion produced customer Macos AND sold the body kits. This car was built by Motion Performance, according to the customer’s specifications. The restoration of this car is said to be “STUNNING!” From the photos I’ve seen, that adjective is spot on.

And Dan McMichaels scores a second stunner. This might be the most amazing Corvette barn find ever. The car was discovered by Maryland State legislator Rick Impallaria when he was clearing out cars and hardware after evicting a tenant from the auto body shop he was renting. Stashed away was the hulk of an unusual Corvette. Rick was told that the car might be the remains of a Motion Can-Am Spyder Corvette. Rick did some inquiries, including to our sister site, www.BaldwinMotionReport.com, as to what the Corvette community thought this hulk might have been. Turns out it was one of three yellow Can-Am Spyder Corvettes built. And now it’s Dan McMichaels. If anyone will “do right” by the Can-Am Spyder, it’ll be Dan!

Vette Videos: 1988 Callaway SLEDGEHAMMER!!!

Dateline: 8.24.11
A crash course on what it takes to build a 250-plus-MPH C4 Corvette

Yesterday we told you about the ASTONISHING 254.76-MPH twin-turbocharged Callaway Corvette. The below video is an excellent presentation of this impressive machine. Reeves Callaway and project manager Tim Good take you on a full tour of the Sledgehammer project. You’ll get to see the Sledgehammer blast the Transportation Research Center in Ohio and even the late John Lingenfelter has a few words to say. Watch this and you WILL be a fan!


The 250-MPH Club has very few members. The astonishing $1,705,769 Bugatti Veyron 16.4 Super Sport that holds the Guinness average top speed record of 267-MPH, but is based on an architecture originally designed to be an all-out race car, not a platform designed in 1980 as a mass-produced sports car. Then there’s the $650,000, 1,287-HP Ultimate Aero built by Shelby Super Cars that’ll do 270-MPH. Granted, the Bugatti and Shelby do things Continue reading “Vette Videos: 1988 Callaway SLEDGEHAMMER!!!” →

The Baldwin-Motion Phase-III GT Corvette – Version 2.0

Published on by Scott

The Phase III GT was only a few months old, and Joel Rosen rolled out an even WILDER version of his ultimate Corvette GT.

A few months after Joel Rosen and Marty Schorr rocked the house at the ‘69 New York Auto Show with the Baldwin Motion Phase III Corvette, plus, got the official blessing from Corvette chief engineer, Zora Arkus-Duntov, the next version of the GT was shown on the September ‘70 issue of High-Performance CARS Magazine. The fixed-headlight was a real polarizer, but it was definitely unique. It’s too bad that federal regulations did not allow for the clear lexan headlight covers, because the covers were available for “show” or “off road” use only, and looked great.

From 1969 to 1971 only 12 Phase III GT Corvettes were built. Due to the extensive custom body work on top of the performance enhancements, the Phase III GT Corvettes were THE most expensive of all of the Baldwin-Motion Phase III Supercars.

Vote For Your Favorite Baldwin-Motion Corvette

Which Baldwin-Motion Corvette is YOUR FAVORITE?

(scroll down to cast your vote)

From 1967 to 1978 Joel Rosen, Marty Schorr, and the crew produced an astonishing array of Chevy supercars. “The Fantastic Five” included the Biscayne, the Nova, the Chevelle, the Camaro, and Corvette. If you wanted a true sleeper supercar, the Biscayne was the way to deliver one heck of a surprise. While the big 427 and 454 monster cars got most of the attention, Mr. Motion would build you whatever you wanted. So, there were also a few Motion cars powered with enhanced 350 small-blocks, and a few Corvettes that received turbochargers!

All of the Baldwin-Motion cars were special and unique, but let’s face it, the Corvettes were the halo cars. Since every Motion supercar was custom-built according to the customer’s wants and checkbook, every car is slightly different. The only thing standard was Joel’s selection of heavy-duty after market parts needed to keep the machine relatively bulletproof.

From ‘68 to ‘78, there were six distinctive Baldwin-Motion Corvettes. Let’s have a look-see… Continue reading “Vote For Your Favorite Baldwin-Motion Corvette” →

John & Burt Greenwood’s C4 Corvette “G” Supercars

Published on by Scott

John & Burt Greenwood Build Super C4 Corvettes

This was to be Greenwood's $425,000 Supervette.

John Greenwood is a Corvette racing legend. Actually, it was the “John and Bert” Greenwood story here because John’s brother Bert was very much part of the story. Through the ‘70s, Greenwood Corvettes were fearsome and very entertaining. It was a classic, American little guy vs the big dogs. The Woodward Avenue street racer put the fear of big-block Chevy power into the competition. While all of the above is correct, sometimes early childhood impressions have profound effects on a lad’s life.

The Greenwood brothers had an inside connection – their Dad. Sr. Greenwood worked at the GM Tech Center and on weekends would take John and Bert to see some of the prototype cars in development. (Can you imagine that?) The inspired boys started their careers with a tube frame go-cart, powered by a Briggs & Stratton lawn mower engine. Not long after getting his drivers license, John was street racing a big-block ‘64 Corvette. Street racing lead to road racing with John winning the A/Production championship in his first year.
