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.
All of the parts I checked follow this rule and are dated

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 "10" is the tenth month of year and the
"03" is the
third day of the month meaning the engine was assembled on

Corvette with an automatic transmission and Federal Emissions, which is correct for this car.

information obtained from Alan A. Colvin's Corvette by the Numbers
and Mike Antonick's Corvette Black Book.
White exterior is in good driver condition. As one can see in
the photos the finish has a nice gloss and shine. Both doors
open and shut nicely. The YJ8 aluminum wheels and center caps
are in beautiful condition with a brilliant finish and no curb
rash. The Cooper Cobra tires are virtually brand new and
correctly sized 255/60R15. As
one would expect from a paintjob with this many years on it there
are some blemishes and signs of age and paint work in the paint around the car.
It basically looks in person as it does in the photos and as
once can see in the gallery below the paint has some crazing and
other spots. As
one can see in the many photos of the underside of the car, the
is very clean and this Corvette has absolutely NO RUST ISSUES.
We have included specific photos of the areas most prone to
rust. 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 C3 Corvette.
Window Date Codes
note that ALL of the glass on this Corvette, even the
date coded and original as each piece predates the car's
body build date of October 18, 1977 (B18). Original
glass is a good indication that this car has had no
major accident history and never sustained significant
The Midnight Blue interior in this Corvette is in good original condition.
The seats look in person they do in the photos and do show
signs of wear from over the years. Please note that these
appear to be the original seats and skins, not some cheap
aftermarket covers or replacements. The carpet is in great condition with no tears or holes. The door panels are in
wonderful shape and, unlike many Corvettes of this age, they fit
well and tight to the door. The dash and console look good with no
sun fading. The jack and jack handle are still with the car,
stored correctly behind the passenger seat, and pictured
The original spare is still with the car and has never been
used. There is a crack in the dash visible in the photos. 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.
Corvette seems to be in very good mechanical condition. The car starts right away every time, runs well, and
idles 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 and the car
performs quite well overall. The brakes are responsive and do
not pull to one side of the other. The transmission shifts well. 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 ignition shielding and smog pump are still in place.
The radio works as do all
the exterior lights, horn, wipers, power windows, and the blower
for the a/c and heat on all speeds. All of the gauges work with
the obvious exception of the clock. The power antenna works as
one can see in the video, which is a very common problem on this
ear Corvette. The vacuum system for the
headlights works great. Also, the headlights go up correctly
with either the headlight switch or vacuum override switch.
There complete operation form both switches can be viewed in the
video below. The car now has true dual exhaust with no catalytic
converter and a very healthy tone. As with many older carbureted
cars, this Corvette is a bit cold blooded. The a/c does not work, but
the system is complete and there is a belt on the a/c compressor
so it may just need freon. Note enough can be said as to how much of a pleasure
it is to drive this car, especially with the-tops out on a
Overall, this 1978 Corvette
great driver condition. The originality,
the low miles, the
beautiful original color combination, and the great overall condition make this car especially important and
hard to duplicate. Numbers matching is very important in
the Corvette market and in Corvette pricing, and as one
can see this car is
remarkably correct and original and there are photos
below of the VIN stamp on the engine block, suffix code,
engine assembly date, transmission VIN stamp, and
transmission casting date. 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.
