The low original mileage is verified not only by the condition of the car, but also the clear Ohio title, showing the mileage as "Actual."

Model Description

Chevrolet marked Corvette's 25th Anniversary in 1978 with the most extensive redesign of the car since the introduction of the C3 body style in 1968. The new Corvette introduced a large fastback style rear window that drastically increased luggage space in the rear compartment behind the seats. The interior of the 1978 was also significantly redesigned. The speedometer and tachometer were redesigned in a more square and vertical mode. A glove box was added on the passenger side to replace the pocket. The door panels were also completely new and included screw on arm rests to replace the molded style that been the standard since 1965. 1978 Corvettes featured special 25th Anniversary emblems specific to that year.

Exterior

The 2-tone Silver and Charcoal exterior is in excellent driver condition. As one can see in the photos the finish has a terrific gloss, deep shine, and smooth finish. Both doors open and shut nicely. The original YJ8 slotted aluminum wheels have a brilliant finish. The Goodyear Eagle GTII white letter tires have about 90% tread left and are correctly sized 225/70R15. There are few small rock chip touch-ups and tiny blemishes that were too small to show up in the photos, but nothing else that is really noticeable from about five or ten feet away. As one can see in the many photos of the underside of the car, it is very clean and this Corvette has absolutely NO RUST ISSUES. The frame is totally solid with no rust around the "key hole" area in front of the rear tire and I have seen no evidence of corrosion around the windshield, which are the two most notorious spots for rust on a C3 Corvette. We have included specific photos of the areas most prone to rust to show how nice this car looks.

Window Date Codes

Please note that ALL of the glass on this Corvette, both pieces of door glass, the rear window, and even the windshield, are all date coded and original as each piece predates the car's body build date of August 21, 1978 (L21). Original glass is a good indication that this car has had no major accident history and never sustained significant damage.

Interior

The Oyster Leather interior in this Corvette is in outstanding condition. The seats look just in person as they do in the photos with no holes, split seams, or excessive wear. The driver's seat is not worn in the typical area on the bolster where the driver gets in and out. The gauge faces are clean and crisp and the lenses are clear. The carpet is also in great condition with no rips or holes. This includes the rear carpet which is often neglected. The dash and console look awesome with no cracks or sun fading. The door panels are in fantastic shape and, unlike many Corvettes of this age, they fit well and tight to the door. The door pulls are solid and intact. The jack and jack handle are still with the car, stored correctly behind the passenger seat. The original spare is still with the car and has never been used. This Corvette has never been smoked in; there are no burns marks and no aroma of cigarettes.

Corvette interiors from this era are not known to wear well, especially with a very light color like Oyster, and the excellent condition of this original interior is a huge testament to the meticulous care and attention this car has received throughout its life and another great verification of the very low original mileage. The original black T-top bags are also included with the car.

Mechanical

This Corvette seems to be in very good mechanical condition. The car starts right away every time, runs well, and idles smooth. It drives great on the road and at highway speeds. In the video below one can observe the car accelerating on the highway up to about 70mph, shifting through all the gears, braking to stoplight, and going through some curves. Please note that there are no strange noises or vibrations and the car performs quite well overall. This Corvette has plenty of power and is quite fast. Also, the engine compartment is beautifully clean, detailed, correct and complete as one can see in the photos. Even the ignition shielding, original air cleaner, original valve covers, and catalytic converter are all still in place.

The radio works as do all the exterior lights, interior lights, indicators, horn, wipers, power windows, and rear window defogger. The blower works on all speeds and the a/c also works and blows cold. One can observe the a/c compressor clicking on and engaging properly in the video. The vacuum system for the headlights works correctly. The headlights go up quickly, evenly, and with no binding in the mechanism. Also, the headlights go up correctly with either the headlight switch or vacuum override switch. There complete operation form both switches can be viewed in the video. All of the gauges work with the obvious exception of the clock. Not enough can be said as to how much of a pleasure it is to drive this car, especially with the T-tops out on a beautiful day.

Overall Condition



Overall, this 1978 Corvette is in fantastic condition. The originality, the very low miles, the desirable color combination, the great options, and the excellent overall condition make this car especially important and hard to duplicate. Ultra low mileage C3 Corvettes, like this car, draw a great premium in the current market. Numbers matching is very important in Corvette pricing and as one can see this car is very correct. There are photos below of the VIN stamp on the engine block, suffix code, engine assembly date, transmission VIN stamp, transmission assembly date, and transmission casting date. This Corvette always gets a ton of attention driving down the road. It is apparent that the vehicle has been well taken care of by its previous owners. The prices of C3 Corvettes have increased considerably over the past several years. They are secure and wise investments for a collector. One could easily enjoy this vehicle for several years and sell it for more than the purchase price with minimal effort.

Thank you for looking and please do not hesitate to email or call with any questions.
