[VIDEO] Follow Along in this Appraisal of a One-Owner 25K-Mile 1966 Corvette L72 Big Block

A remarkably original 1966 Chevrolet Corvette—still owned by the widow of its late original owner—was recently inspected in Michigan by classic car appraiser Jason Phillips, who documented what he described as an unusually authentic survivor level C2 big block.

Phillips, a Detroit area specialist known for deep dive inspections of collectible Corvettes, spent several hours evaluating the 427/425 horsepower IP suffix car, despite temperatures hovering around 15 degrees.

“What a treat today in this blistering cold Michigan weather. That’s probably 15 degrees out today,” he said as he began his walk-around.

The car, showing 25,510 actual miles, retains an extraordinary amount of factory originality. Phillips verified the numbers matching engine block, Holley carburetor list number, close ratio Muncie transmission, and 4.11 Positraction rear end, along with the trim tag, VIN tag, and even the original invoice and tank sticker.

“What you’re looking at is original factory applied code 978 Laguna blue paint,” Phillips said. “Not a repaint in original color. Factory applied paint. So, not something we get to see too often.”

He also noted the presence of factory bonding strips—a telltale sign of untouched fiberglass panels—still visible beneath the lacquer.

The extreme cold prevented Phillips from getting the big block to fire consistently, though he made several attempts.

“Alright, let’s try one, two, three, and see what that gives us,” he said during one cranking attempt. “Oh, she’s wanting to. It is cold. Well, if you live in Alaska, this might not be the car for you.”

The car showed oil seepage and a coolant leak at the lower radiator hose collar, but Phillips emphasized that these issues are typical for a long stored vehicle.

Suspension components—including riveted ball joints, control arm bushings, and much of the original hardware—appear untouched. The frame, dog legs, and caps were described as being in “marvelous shape,” with clean floor tubs and intact fiberglass stranding.

Inside, the Corvette retains its teakwood steering wheel, AM/FM radio, tinted glass, and original loop style carpet. Phillips highlighted the authenticity of the cabin materials.

“That dash is as close to perfect as they get,” he said. “Look at those original fitted Chevrolet plastic mats. Pretty cool.”

Seat stitching, pedal wear, and interior trim all aligned with the car’s low mileage history.

The chrome bumpers, rocker moldings, and glass date codes all appear original. Phillips pointed out minor lacquer checking, small chips, and a thin paint stain caused years ago by a fuel drip—an imperfection the owner’s widow said had always bothered her husband.

“Typical paint contusions and nicks that you would see on paint that could be potentially as old as your grandfather,” Phillips noted.

Underneath, the Corvette still wears its original exhaust shields, spare tire carrier, and many factory fasteners. Some splash shields are missing, and the shocks appear to have been replaced long ago, but the overall structure remains impressively intact.

“These steel wheels have been repainted, by the way,” Phillips said, noting the tri spinner hubcaps and period correct whitewalls.

After nearly 40 minutes of inspection in sub freezing conditions, Phillips summed up the car’s significance:

“So, the wrap up summary is that it’s a very nice original survivor car. A lot of people say, ‘Look at my survivor car,’ and then they don’t really have a survivor car. This is an exception to the rule for the reasons mentioned earlier. It really is a nice, nice, nice survivor. Great color combination.”

Though the cold prevented a full test drive, Phillips verified lights, signals, power windows, radio functions, and other electrical components before concluding the session.

“Jason from Auto Appraised wrapping it up on this cold day,” he said. “If you need an inspection similar, 800-301 3886. Have a nice day.”

Be still, my heart. What a jewel.

OMG! you might know all about Corvettes, but you sure don’t know how to start a car that hasn’t run for years. All that grinding just made me cringe. If you had half a brain, you would have filled the carburetor with gas. It’s a wonder the starter held up. Also, have someone that knows engines tell you why you should never hold the clutch in while trying to start an engine that again, hasn’t run for years, hint: it’s hell on the thrust surface of the rear main bearing.
