Excellent Condition, 4-Speed Manual Transmission, Low Miles, #'s Match

….

Please call Matt directly at 513-708-1468 with any questions about this car.

Seven Hills Motorcars is proud to offer this beautiful 1980 Corvette in excellent condition with a 4-Speed manual transmission and only 62,958 original miles. This Corvette looks fantastic, runs great, and is an excellent driver. The 4-Speed manual transmission is exceptionally rare in a late C3 Corvette. The manual transmission examples are highly desirable and draw a good premium over a standard 1980 Corvette with an automatic transmission. The Frost Beige (59_ over Doeskin Leather (592) interior is a beautiful color combination that looks stunning on the car. It is also the correct and original color scheme as verified by the codes on the trim tag and the window sticker.

This 4-speed Corvette comes with a wealth of original documentation. Included with the car is the ordinal window sticker, that confirms all the desirable options the car came with, the original sales invoice that shows the original owner traded in a 1977 Corvette when he purchased this car, the warranty information booklet, and many receipts from the 80's for maintenance that total almost $4,000.

Besides the correct paint and trim codes this Corvette is "Numbers Matching" meaning the engine in the car is the factory correct original engine that was installed in the car new in St. Louis in 1979. The last six digits oof the VIN, 425384, are stamped on the engine pad which indicates the engine is original. The last six digits of the VIN are also stamped on the main case of the transmission and pictured in this ad and the transmission is also original. Besides the engine and transmission almost every part we checked on the car is correct with the proper part numbers and appropriate date codes. We have run the numbers on literally hundreds of Corvettes over the years and there are very few that are so correct and original. Even very detailed parts like the starter, alternator, carburetor, and distributor are all correct and original.

In addition to the 4-speed transmission, this Corvette is loaded with other highly desirable options such as glass T-Tops, N90 aluminum wheels, air conditioning, tilt and telescopic steering column, and power antenna.

This is an excellent opportunity to own a classic Corvette that is ready to be used and enjoyed at an unbeatable value. One could easily buy this car now and sell it for more than the purchase price in years to come as the market on the 1980 and 1981 Corvettes is strong right now and on the rise. In our experience the 1980 and 1981 model years draw a good premium over other late C3 Corvettes; this is especially true for very low mileage and manual transmission examples like this car. The low original mileage is verified not only by the condition of the car, but also the clear Ohio title, pictured in this ad, showing the mileage as "Actual." Please peruse all of the photos, the extensive list of numbers, video, and information to get a true sense of how nice, clean, and original this Corvette really is.

As a side note, this Corvette is not a dealer auction vehicle. We hand pick each car after careful inspection. Our Corvettes come from owners who expect their car to go to someone that will give the vehicle the same care and attention as they did. We invite and encourage you to examine the car in person or have the car inspected. Please take the time to scrutinize each picture. We photograph each vehicle to the greatest extent so you can feel confident about your purchase. If you have a question about the Corvette, just give us a call.

Exterior

The Frost Beige exterior is in very nice 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 N90 aluminum wheels are in beautiful condition with a brilliant finish and no curb rash. The Goodyear Eagle raised white letter tires have plenty of tread left and are sized 225/70R15. There are no major imperfections that have been intentionally excluded from the photos. There are some small touch ups and very tiny blemishes that were too tiny to show up in the pictures, but nothing that is really noticeable from about five or ten feet away. There is one small imperfection on the right front corner, which is visible in the photos. This Corvette has absolutely no rust issues. As one can see in the many photos of the underside of the car, this car is very clean underneath. The frame is totally solid with no rust around the "key hole" area in front of the rear tire and we 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 almost all of the glass on this Corvette, even the both T-Tops, is date coded and original as each piece predates the car's body build date of December 9, 1979 (C09). Original glass is a good indication that this car has had no major accident history and never sustained significant damage.

Interior

The Beige Leather interior in this Corvette is in nice condition. The seats are look as good in person as they do in the photos with some typical wear on the bolster where driver gets in and out. The gauge faces are crisp and clean and the lenses are clear. The carpet is also in great condition with no major stains and a spot of wear in the left wheel well. This includes the rear carpet, which is often neglected. The dash and console look great with no cracks or sun fading. The door panels are in nice shape overall. The jack and jack handle are still with the car, stored correctly behind the passenger seat. The original spare is still with the car. 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 and the excellent condition of this interior is a huge testament to the meticulous care and attention this car has received throughout its life and another great verification of the low original mileage.

Mechanical

This Corvette seems to be in very good mechanical condition. The car starts right away every time, runs well, and idles well. It drives great and feels nice on the road and at highway speeds. In the video in this ad 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 vibrations or strange noises and the car performs quite well overall. The shifter is tight, does not grind, or pop out of gear. The clutch feels good. This Corvette has plenty of power and is quite fast. Also, the engine compartment is beautifully clean, detailed, and correct as one can see in the photos, even the original ignition shielding, smog pump, and catalytic converter are all still in place.

The horn works as do all the exterior lights, interior lights, wipers, power windows, power locks, dash lights, and indicators. The power antenna works with a switch. The blower for the heater and a/c works on all speeds. The a/c itself works and one can see the a/c compressor engaging properly in the video. All of the gauges work with the obvious exception of the clock. Even very detailed items that many buyers do not even know to check for work on this car such as the interior delay light timer and the cargo light by the spare tire. The vacuum system for the headlights works correctly. Also, the headlights go up properly with either the headlight switch or vacuum override switch. Their complete operation from both switches can be viewed in the video below. Not enough can be said as to how much of a pleasure it is to drive this car, especially with the 4-speed manual transmission and the T-tops out on a beautiful day.

Overall Condition



Overall, this 1980 Corvette is in magnificent driver condition. The 4-Speed manual transmission, the low original mileage, and the excellent overall condition make this car especially important and hard to duplicate. Numbers matching is extremely important in Corvette pricing and as one can see this car is very correct. 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. 4-Speed examples like this car always draw a premium over the automatic transmission cars. 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.
