In the more than 33 years that he has been an NCRS member, Roy has been active in all phases of the hobby and the organization. Roy has been instrumental in the NCRS effort working with Barrett-Jackson to improve the accountability of the statements and documents being presented with vehicles crossing their auction block. NCRS has developed and Barrett-Jackson provides not only the Award Confirmation Document Service, which documents any judging records on a specific vehicle within NCRS, but also in a more recent development, NCRS now provides a Document Validation Service for any documents provided as GM-issued for each 1962 through 1975 Corvette entered in the auction.
Thanks to his close association with General Motors, well-known Corvette enthusiast Roy Sinor was able to create this special matched set of 1994 and 2009 Corvette ZR1s, both serial number 5800074. Literally “one of one,” they’ve been prominently displayed at the National Corvette Museum in Bowling Green, Ky. Sinor emphasizes that these are his personal cars, which he intended to own forever. Circumstances have changed, however, and he decided to sell the two cars, which will be sold only as a pair. This is a once-in-a-lifetime chance to own a unique set of celebrity Corvettes that bring a whole new meaning to the term “matching numbers.”
Sinor, president of Sinor Prestige Automobiles, is a prominent collector, popular concours judge and professional consultant with a client list that reads like a Who’s Who of the collector car hobby. A graduate mechanical engineer, he’s been an active member of the NCRS for more than 33 years. He frequently contributes to Corvette Market magazine and is considered one of the most knowledgeable Corvette experts in the world.
In 1984, Chevrolet finally introduced a new Corvette. The C4 is better in almost every way than the “Coke bottle” cars of 1968 through 1983…streamlined, modern and capable of world-class performance. Two years later, General Motors bought ailing Group Lotus and promptly put Lotus engineers to work on an aluminum block V8 with double-overhead camshafts and four valves per cylinder. The Lotus-engineered production LT5 engines were actually assembled by Mercury Marine, then shipped to the Corvette assembly plant in Bowling Green. In addition, Lotus racing engineers helped develop the FX3 adjustable ride control suspension that would be standard on every one of these special Corvettes.
The ZR1 was available only as a coupe with a 6-speed manual transmission, ordered as a Special Performance Package that nearly doubled the price of a standard Corvette. Along with the special engine, the ZR1 package added a wider rear body highlighted by four square tail lamps in a convex fascia, 11” wide rear wheels and a high-mounted center brake light.
After its debut in 1990, the ZR1 was improved each year. By 1994, engine modifications raised output to 405hp @ 5,800 rpm and 385 ft/lb @ 5,200 rpm. Traction control, additional ZR1 badging and improved emissions systems also made 1994 the ultimate C4 ZR1, since the model continued into 1995 unchanged. Over six years, 6,939 C4 ZR1 Corvettes were built, and all were considered collectors items from Day One.
But some ZR1s are more collectible than others. Sinor’s 1994 ZR1 is the 74th built in 1994 and is documented as the only Admiral Blue with Torch Red interior ZR1 in existence. According to his research, every other C4 ZR1 built was a duplicate of at least one other car. In other words, serial number 5800074 is the only totally unique C4 ZR1, literally one of one. This color combination turned out to be so striking, it was later selected by Chevrolet stylists as the scheme for the limited-production 1996 Grand Sport.
Malcolm Konner Chevrolet in Paramus, N. J., specialized in unusual Corvettes, and this car had been special-ordered for Konner’s son, Gary. It has every possible option, including a glass roof. The MSRP was a whopping $69,043 in 1994, a far cry from the $36,185 of that year’s base Corvette. It comes with complete documentation and literature, has never been wrecked, repainted or damaged, and earned an NCRS Chapter Top Flight certification. The odometer reads just over 11,000 miles.
In 2009, Chevrolet revived the ZR1 concept. The C6 Corvette was already one of the most exotic high-performance Sports cars in the world, especially in Z06 trim. In simple terms, to create the new ZR1, Corvette engineers started with the Z06, including its expensive aluminum chassis and magnesium suspension pieces. They added a Roots supercharger to the already potent LS3 V8, creating a monster called LS9 that produces 638hp @ 6,500 rpm and 604 ft/lb of torque @ 4,000 rpm. Coupled to a close-ratio 6-speed gearbox with heavy-duty twin-disc clutch, it drives the 3,364-pound ZR1 from 0 to 60 in 3.3 seconds and up to 205 mph. That not only makes the ZR1 the fastest production Chevrolet ever, but world-class, right up there with Porsche 911 Turbos and Ferrari 458s.
The ZR1 is far from one-dimensional. It was given huge carbon/ceramic disc brakes with drilled rotors, 15.5” in diameter in the front, 15.0” in the rear. The front wheels are 19” and the rears 20”, both shod with wide Michelin Pilot Sport tires. The ZR1 pulls a remarkable 1.05 G on the skidpad. Two-mode magnetic suspension damping, carbon fiber bodywork with a clear Lexan panel over the engine and a variety of performance tweaks enabled a stock ZR1 to set a one-lap record of the demanding 12.944 mile Nordschleife loop of the Nürburgring at 7:26.4, a time that is 23 seconds faster than that set by a comparable Z06.
When the new ZR1 appeared, Sinor knew he’d been given a unique opportunity to create a pair of matching number ZR1s. Because of his fame in Corvette circles, he was able to do a VIP Delivery of a 2009 ZR1 with serial number 5800074, matching that of the Konner 1994 ZR1 already in his garage. Even a VIP can no longer order a matching serial number ZR1, so this C4/C6 pair will always remain unique.
The C6 ZR1 was ordered in Jet Stream Blue, which is very close to the Admiral Blue of the 1994 ZR1. As Sinor says, “I actually tried to get a red interior to match the C4 car, but since they didn’t offer a red interior in 2009, it was just not a string that I could pull within General Motors.” So his car has an Ebony/Titanium interior and every available option, including chrome wheels. MSRP is $122,800. Like the C4, it also has roughly 15,000 miles on the odometer and is essentially brand new in every way.
Sinor was able to do the Factory Buyer’s Tour and spent two days on the assembly line watching 5800074 be built. He was the first person to start the engine and drive it off the assembly line for Museum Delivery. He has records, photos and documentation of all that. Since then, it has been coddled as part of his personal collection. Obviously, when Sinor’s C6 ZR1 is paired with the Gary Konner C4 ZR1, this is a truly special pair of matching serial number, celebrity-owned cars for a die-hard Corvette collector or museum — a set that can never be duplicated.
