Chevrolet in St. Mary's, Ohio on March 31, 1981.
The car is totally solid with nice lines and no rust issues.
The Frost Beige over Doeskin color combination looks great 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, as well as the build sheet. This is an excellent opportunity to own a classic Corvette
that is ready to be used and enjoyed at an unbeatable value. One

price in years to come as the market on the 1980 and 1981 Corvettes
is strong right now and on the rise. 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, list of numbers, video, and information below to get a true sense of
how nice and clean 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.
Most of the parts I checked follow this rule and are dated
The first digit, "1," indicates that the US is the country
of origin. The "G" is the manufacturer, GM. The third digit,
"1," is the make, Chevrolet. The fourth digit, "A," is the
restraint system, manual belts. The fifth digit, "Y," is the
series, Corvette. The "87," is the body style, 2-door sport
coupe. The eighth digit "6" is the engine, L81. The ninth
digit is a check that car vary from car to car. The tenth
digit, "B" is the model year, 1981. The "S" is the plant
where the car was produced, St. Louis. The last five digits
are a sequence number so this is the 23,669th Corvette made
for 1981 in St. Louis.
Body Build Date
"H" corresponds to March, and "19" is the
nineteenth day of the
month meaning this Corvette's body build date is March 19, 1981.
"V" means the engine was build in the Flint, MI plant.
The "03" is the third month of year and the
"10" is the
tenth day of the month meaning the engine was assembled on
March 10, 1981. This is correct as it precedes the build
date of the car.
This means the motor was intended for an L81 Corvette with a
manual transmission, which is correct for this car.
Engine VIN Stamping
The last 6 digits of the car's VIN,
423669, are stamped on
the engine pad meaning this engine is original to this car.
Engine Block Casting Number
The engine block has the correct 10410207 casting number,
which is correct for a 1981 Corvette.
Engine Block Casting Date
C 6 1
"C" is March, "6" is the
sixth day of the month, and the
"1" is the last digit of the calendar year so the engine
block was cast on March 6, 1981, which is correct as it
predates the assembly date.
Intake Manifold Casting Number
The intake manifold has the correct 14007376 casting number.
Transmission Main Cast Casting #
1304 065 906
The main case of the transmission has the correct 1304 065
906 casting number.
Transmission Casting Date
12 17 80
The "12" would be the twelfth month of the year. The "17" would
be the seventeenth day of the month and the "80" would be 1980 so
the main case of the transmission was cast on December 17,
Transmission Assembly Date Code
The "W" indicates this is a Borg Warner transmission. The
"C" is the month it was made, March. The "11" is the
eleventh day of the month. The last "1" is the year, 1981.
The "2," indicates that it was made during the second shift.
So the transmission was assembled on March 11, 1981.
Transmission VIN Stamp
The last 6 digits of the car's VIN, 423669, are stamped on
the main case of the transmission and pictured below meaning
this transmission is original to this car.

Beige exterior is in nice 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 tires are sized 225/70R15, which is correct
according to the factory build sheet. There
are a some faint imperfections and touch ups around the car that
are too tiny to show up in
pictures, 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, this Corvette has NO RUST ISSUES. The frame is totally
solid with no rust around the "key hole" are 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.
Doeskin Tan interior in this Corvette is in spectacular
condition. The seats look just virtually brand new with no rips, split seams, or
and signs of
wear. They are not worn in the typical
area where the driver gets in and out. The carpet is also in
great original condition with no major stains or holes. This
includes the rear carpet, which is often neglected. The door panels are in
wonderful shape and,
unlike many Corvettes of this age, they fit well and tight
to the door. The door pulls are solid and intact. There is
one spot on the right corner of the dash where it is
cracked, but as one can see in the photos is it not too
noticeable. The parking brake handle also has a crack. The
console is in nice shape with no sun damage, but a couple
switches are loose in their housings. The spare tire carrier
is still on the car, but there is no tire inside. 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
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 good mechanical condition. The car
starts right away every time. 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. The transmission shifts
well and does not pop out of gear. The clutch feels good. This Corvette has plenty of
power and is quite fast. The previous owner installed a new cam
that gives the car some extra power and a nice rumble at idle. Also, the engine compartment is
beautifully clean and detailed as one can see in the photos. The
horn works as do all the exterior lights, wipers, power windows,
power seat in all directions, all
of the gauges, and even the clock works. The speedo needle can
be a bit bouncy. The blower works on one speed from a switch in
the glove box. The a/c system is totally complete and there is a
belt on the compressor, but the a/c does not work so the system
may need to be recharged. The vacuum system for the
headlights works correctly. Also, the headlights
go up properly with either the headlight switch or vacuum
override switch. There is a small coolant leak near the lower
hose connection to the radiator and the check engine light does
not work. There is a slight sound of an
exhaust leak, which is very common on 1981 Corvettes, but it
becomes less noticeable when the car warms up. 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, this 1981 Corvette is in
wonderful driver condition. Numbers matching is extremely
important in Corvette pricing, especially with low
mileage examples like this car. One of the most
appealing features of this Corvettes is the original
4-Speed transmission, which is quite rare and very
sought-after. The originality, the
great 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.
