Seven Hills Motorcars is glad to offer this low mileage and
completely numbers matching 1978 Silver Anniversary Edition Corvette
that is an excellent driver and priced to sell. The car is totally
solid and rust free and has a recent beautiful professional paint
job. It runs great and is a blast to drive. The Corvette is finished
in the beautiful and highly desirable color combination of RPO B27
Silver Anniversary Two Tone over Mahogany Cloth interior, which is
the correct and original color combination as verified by the codes
on the trim tag, pictured below and also the original window sticker
enclosed. Most Anniversary Edition Corvettes have Oyster interior.
Mahogany is much more rare, striking, and attractive in my opinion.
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
with minimal work and effort. The low mileage is supported not only
by the condition of the car, but also the clear Ohio title that
states the mileage as, "Actual." Please peruse all of the photos,
numbers, and video below to get a true sense of how original and
correct this Corvette really is
Please notice that all 1978 Corvettes wore the "25th
Anniversary" badge. However, only certain cars, such as this
example, were the actual Silver Anniversary Editions with
the Silver Anniversary regular production order (RPO),
"B2Z." This is verified by the trim tag that is pictured
below showing the paint to be 13 for the bright Silver upper
sections and 07 for the Dark Gray lower section, which was only used in 1978 and only for
the B2Z Corvettes, on the darker lower portion.
The B2Z option is also verified by the original window
sticker, which is pictured below.
This Corvette is completely "Numbers Matching" and virtually
every part we checked on the car is correct. We have run the
numbers on hundreds of Corvettes and there are very few that
are so many correct and original components with correct
numbers and dates. The last six digits of the VIN are
stamped on the engine pad, which is pictured below, and the
engine is original to the car. The transmission is also
original with the last six digits of the VIN stamped on the
main case and pictured below.
Included with the car is a great amount of original
documentation and dozens of receipts, an original title from
1982, and other bits of the car's history. The original
window sticker is still with car, which is especially
important for this Corvette as it verifies as original the
many highly desirable options like the B2Z paint, FE7
Gymkhana suspension, and YJ8 Aluminum wheels. The original
new car inspection form from Brown Co Motors, where the car
was sold new is still with this Corvette along with the
original warranty book, original owners manual, EPA fuel
sticker, battery pamphlet, battery information, consumer
information booklet, and blower motor information form,
which all came with the car when it was sold new.
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.
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.
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
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,
L, correct for an L48 car. The sixth digit, "8," indicates
the model year, 1978. The "S" is the plant where the car
was produced, St. Louis. The last five digits are a

"24" is the
twenty-fourth day of the month meaning the engine was assembled on

The "8" is the last digit of the calendar year, the "B"

and original Quadrajet produced by Carter

L48 Corvette with an automatic transmission and a/c. The fourth digit,
"5," means the carb was built in the 1976 - 1979 production
run. The fifth digit, "8," means it was built for the 1978
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 firth two digits, "75," indicate the

information obtained from Alan A. Colvin's Corvette by the Numbers
and Mike Antonick's Corvette Black Book.
The Two Tone
Silver (13) and Charcoal (07) exterior is in excellent driver
condition. As one can see in the photos, the paint has a
terrific gloss, deep shine, and smooth finish. Often Corvettes
will have particularly chipped up front ends, this car does not.
There are no major scratches, scrapes, or other imperfections
that have been intentionally excluded from the photos. There may
be some small blemishes that were to small to show up, but
nothing that is really noticeable from five feet away. The
original YJ8 aluminum wheels are in great shape with a brilliant
finish and no curb rash. The Goodyear Eagle ST tires have great
tread left and are sized 255/60/15. There are NO RUST ISSUES
WITH THIS CAR as one can see in the many photos of the
underside. The frame is totally solid with no rust around the
"key hole" area in front of the rear tire and there are no signs
of corrosion around the windshield, which are the 2 most
notorious areas for rust on a Corvette of this era.
Window Date Codes
Please note that ALL of the glass on this Corvette, both
side windows, the rear window, and even the windshield
are all date coded and original as each piece predates
the car's body build date of May 5, 1978 (I05).
Original glass is a good indication that this car has
had no major accident history
and never sustained significant damage.
The car looks just as good in person as it does
in the photos.
The Mahogany Cloth interior of the Corvette is in splendid
condition. The seats are in excellent condition with no
rips, seam splits, or excessive wear. Please note that these
appear to be the original seats, not some cheap aftermarket
replacements or covers. The original carpet is in good
condition with no notable stains, rips, or holes. This
includes the rear carpet with is often neglected. The door
panels are in superb shape with no cracks or rips and both
door pulls are solid and in tact. Unlike many Corvettes of
this age, the door panels actually fit well and tight to the
door. The console is in good condition with no cracks, sun
damage, or fading. The dash is in amazing condition with no
sun damage, cracks, or fading. The original stereo is still
in the car but is currently not working. This car has not
been smoked in and there is no cigarette aroma whatsoever.
The original pedal pads are not excessively worn and, as one
can see from the pictures, show normal wear for car with
this mileage. Corvette interiors are not known to wear well
and the amazing condition of this original interior is a
testament to the meticulous care this car has received
throughout it's life.
The interior looks just as good in person as it does in the
This Corvette is in great mechanical condition and it is ready
to be enjoyed. The original numbers matching engine is in great
running condition. The car starts right away every time, runs
well, and idles well. It drives terrifically and it is smooth on
the road and at highway speeds. In the video below one can
observe the car accelerating on the highway up to about 70mph,
braking to stoplight, going through some curves, and shifting
through all the gears. Please note that there are no strange
noises or vibrations 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 pretty fast.
There is no blue smoke when starting or driving the car. When
started cold the car initially goes into high idle as it should
and after a couple minutes properly goes into normal low 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, all gauges (even the clock works), turn
signals, wipers, and blower for the heater and a/c on all
speeds. The a/c on this Corvette works and blows cold. One can
observe the a/c compressor engaging properly and turning on in
the video below. The entire vacuum system for the headlights
works correctly with no effort or binding in the mechanism.
Also, the headlights go up correctly with either the headlight
switch or vacuum override switch. Their complete operation from
both switches can be observed in the video below. As with many
C3 Corvettes there is a little float feeling from the back end
at certain speeds. Not enough can be said as to how much of a
pleasure it is to drive this car, especially with T-tops out on
a beautiful day.
The car runs
and drives just as great as it looks.
Overall, this 1978 Corvette is in
great condition and would make an excellent driver.
Special and Anniversary Edition Corvettes always draw a
premium over their standard Corvette counterparts.
Matching numbers is very important in Corvette pricing
and as one can see this car is very correct. The prices
of C3 Corvettes have increased drastically over the past
years. This is especially true with the Silver
Anniversary Editions in our experience. These cars have
been catching up to the '78 Pace Cars in value and many
people, myself included, prefer the Anniversary Edition
over the Pace Car. This Corvette always gets a ton of
attention driving down the road. It is very apparent
that the vehicle has been well taken care of by its
previous owners. The Silver Anniversary Edition
Corvettes 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.
