1981 Corvette in spectacular condition with the very rare 4-Speed
manual transmission and only 27,221 original miles. This Corvette
looks fantastic, runs great, and is an excellent driver. The Frost

on the car. It is also the correct and original color scheme as
verified by the codes on the trim tag, which is pictured below. This is an excellent opportunity to own a classic
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 and the 4-Speed models draw a
huge premium over automatics. The low original mileage is
verified not only by the condition of the car, but also the clear
Ohio title, pictured below, showing the mileage as "Actual." Please peruse all of the
photos, the extensive list of numbers, video, and information below 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.
Please note when checking the numbers that not only do the
correct stampings and casting numbers appear on the parts, but
all of the dates are also chronologically correct. This
means that all of the parts were made and assembled in the
correct order. For example, all of the dates for the
individual engine components and the engine casting date should
obviously precede the assembly date of the engine because the
parts had to be produced before they could be assembled.

Beige exterior is in
great driver condition. As one can
see in the photos the finish has a terrific gloss, deep shine, and
smooth finish. Both door open and shut nicely as do the hood and headlights.
The N90 aluminum wheels and center caps are in
beautiful condition with a brilliant finish and no curb
rash. The BF Goodrich Radial tires have about 90% tread left and are correctly sized 255/60R15.
There are no major imperfections that have been intentionally
excluded from the photos. There are some touch-ups and other
small blemishes around the car that were too tiny to show up in
the pictures, but nothing that is really noticeably from about
ten feet away. This Corvette has no rust issues. The underside
of the car is exceptionally clean and we have include many
photos below with specific photos of the areas most prone to
rust. The frame is
solid 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
The car looks just as good in person as it does
in the photos.
Camel Leather interior in this Corvette is in spectacular
original condition. The seats are in great condition
and look as good in person as they do in the photos. There is just a small bit of wear in typical
area where the driver gets in and out and a specific photo
the area below. Please note that these are the original
seats and skins, not some cheap aftermarket covers or
replacements. The carpet is good condition with no
holes, tears, or stains. This
includes the rear carpet, which is often neglected. The
gauge faces are clean and crisp and the lenses are clear. The door panels are in
nice shape overall and the door pulls are solid and intact. The dash
and console look awesome with no cracks or sun fading. The
jack and jack handle are still with the car, stored
correctly behind the passenger seat, and pictured below. The original spare is
still with the car and still has the nubs on it. 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
original interior is a huge testament to the
meticulous care and attention
this car has received throughout its life.
The interior looks just as good in person as it does in the
This Corvette seems to be in very good mechanical condition. The car
starts right away every time, runs well, and idle smooth. It drives great and feels nice 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 vibrations or
and the car performs quite well overall. There is no blue smoke
when starting or driving the car. 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 upper ignition shielding, smog pump and original
catalytic converter are still
horn works as do all the horn, exterior lights, wipers, power windows,
and rear window defroster. The "check engine" light works
properly. The blower works on all speeds. The a/c
works and blows cold. One can observe the a/c compressor
engaging properly in the video. The vacuum system for the
headlights works correctly. Also, the headlights
go up properly with either the headlight switch or vacuum
override switch. There complete operation form both switches can
be viewed in the video below. 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.
Also, for any 1981
Corvette you may look at, be sure to verify that the
"check engine" light is working correctly. The light
should go on when the key is turned on as a confirmation
that the light is working, then quickly go off when the
car is started. A great number of these 1981 Corvettes
have had the bulb removed to mask other problems. As one
can observe in the video the "check engine" light on
this car operates just as it should, going on with the
car as a check and then going off when the engine is
The car runs and
drives as well as it looks.
Overall, this 1981 Corvette is in
magnificent driver condition. Manual transmission
Corvettes from this era are rare and command a huge
premium over a car with an automatic transmission. Numbers matching is extremely
important in Corvette pricing, especially with low
mileage examples like this car, and as any buyer can see
this Corvette is extremely correct. The originality, the
very low miles, the 4-Speed transmission, the excellent overall condition, and the great extent to which the
numbers match make this car especially important and
hard to duplicate. 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.
