Seven Hills Motorcars is
Cincinnati's premier Corvette specialist anda licensed and
registered auto dealer by the State of Ohio. With many years of
focused experience we specialize in 1957 to 1982 Corvettes and other GM
classics. There is no other dealership that can better meet your needs
if you would like to buy, sell, or just find out more information about
your Corvette, Cadillac, Camaro, or Trans Am. Founded in 2005, this is
a very focused operation. We do it because we enjoy it. We are a
collectors and enthusiasts; therefore we look for cars that excite us.
I do not purchase at dealer auctions; each car is hand picked because it
is special or rare and because we like it.

Seven Hills Motorcars is
proud to offer this
1980 Corvette in excellent driver condition and with only 59,145 original
miles. This Corvette looks fantastic, runs great, and is an
The car is totally solid with nice lines and no rust issues.
It is also "numbers matching" with the last 6 digits of the car's
VIN, 403308, stamped on the engine pad and pictured below indicating
that this is the original engine that was installed new in the car
at the factory.
Silver Metallic over Red Leather is one of the most
striking and desirable color combinations available and 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. Besides the beautiful colors, this Corvette is loaded with
great options such as the N90 aluminum wheels and and glass
T-Tops. 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. 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 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," indicated the Chevrolet division of
GM. The "Z" is the series, Corvette. The "87" is the body
style, 2-door sport coupe. The fifth digit is the engine, 8,
correct for an L48 car. The sixth digit, "A," indicates the
model year, 1980. The "S" is the plant where the car was
produced, St. Louis. The last five digits are a sequence
number so this is the 3,308th Corvette made for 1980.
Body Build Date
"A" corresponds to
October, and "24" is the
twenty-fourth day of the month meaning this Corvette's body
build date is October 24, 1979.
"V" means the engine was build in the Flint, MI plant.
The "10" is the tenth month of year and the
"20" is the
twentieth day of the month meaning the engine was assembled on
October 20, 1979. This stamping was difficult to read
and pictured below. This is correct as it precedes the build
date of the car.
This means the motor was intended for an L48 Corvette with an
automatic transmission, which is correct for this car.
Engine VIN Stamping
The last 6 digits of the car's VIN,
403308, 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 1980 Corvette.
Engine Block Casting Date
J 3 9
October, "3" is the third day of the month, and the
"9" is the last digit of the calendar year so the engine
block was cast on October 3, 1979, which is correct as it
predates the assembly date.
Intake Manifold Casting Number
The intake manifold has
a14014432 casting number,
which was used L82 Corvettes in 1980.
The distributor is original and correct for a Corvette with
an automatic transmission with a 1103353 stamping.
Distributor Date Code
The "9" is the last digit of the calendar year, the "J"
denotes September, and "14" is the fourteenth day of the month
meaning the distributor was made on September 14, 1979. This
is correct as it predates the assembly date of the engine.
The "170" means the carb was produced after 1976. The fourth
digit, "8," means the carb was built in the 1980's. The
fifth digit, "0," means it was built for the 1980 model
year. The six digit, "2," indicates that it is a 4BBL carb.
The seventh digit, "0," means is was built for the Chevrolet
division of GM. The last digit, "4," means it was intended
for use in an automatic transmission car such as this.
Carburetor Date Code
The "283" is the
283rd day of the year and the last "9" is the last
digit of the calendar year so the carburetor was made on
October 9, 1979.
Exhaust Manifold Left
The left exhaust manifold has the correct 3932461 casting
number for a 1980 Corvette.
Exhaust Manifold Right
The right exhaust manifold has the correct 3932461 casting
number for a 1980 Corvette.
Transmission Date Code
The "Y" is a code that indicated the plant where the car
transmission was produced. The "0" is the year, 1980. The
"R" is the tenth month of the year and the "04" is the
fourth day of the month. The "N" is the shift in which the
transmission was made. This would mean the transmission was
made during the night shift on October 4, 1979.

and Mike Antonick's Corvette Black Book.
The Silver exterior is in nice driver condition. As one can
see in the photos the finish has a terrific gloss, deep shine, and
smooth finish. The N90 aluminum wheels and center caps are in
beautiful condition with a brilliant finish and no curb
rash. The tires have about 90% tread let and are correctly sized 255/60R15.
As one would expect for a paintjob with this many years on it there are
some scratches, touch-ups, and other
blemishes around car
that are visible in the photos and some other that were too tiny
to show up. 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
Red Leather interior in this Corvette is in spectacular
condition. The seats are in excellent shape and look
virtually brand new
with no split seams or any signs of wear. They are not worn
at all in the typical area where the driver gets in and
The carpet is great condition with no rips or
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. The dash and console look awesome with no
cracks or sun fading. 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.
The original T-Top bags
are also included with the car and pictured below.
This Corvette seems to be in
good mechanical condition. The
car starts right away every time and runs well. 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 65mph, 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 brakes are responsive and do
not pull to one side or the other. This Corvette has plenty of
power and is quite fast. Also, the engine compartment is
beautifully clean and detailed.
The radio works
as do all the exterior lights, interior lights, wipers, and power windows. The
blower for the heater and a/c works on all speeds. All of the gauges work
with the obvious
exception of the clock. 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 form both switches can be viewed in the
video below. This Corvette originally came from the factory with
a/c, but the compressor has been removed. The horn does not
work, the faceplate on the radio it a bit loose, and the power
locks only work to lock the driver's door. 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
Overall, this 1980 Corvette is in
excellent driver condition. 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
beautiful and desirable original color combination, 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
cared for 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.
