Chevrolet 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 "37" 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 "05" is the fifth month of year and the
"04" is the
fourth day of the month meaning the engine was assembled on

automatic car such as this.

129th day of the year
and the last digit, "8," is the last digit of the calendar
year so this carburetor was made on May 8, 1978.

exterior is in fantastic driver condition. As one can see in the
photos, the paint has a dazzling gloss, deep shine, and smooth
finish. Both doors open and shut nicely.
The YJ8 aluminum wheels are in excellent condition with a
brilliant finish and no curb rash. The previous owners said he
recently replaced the tires and they have about 90% tread left. There are no major imperfections that have been
intentionally excluded from the photos. There are some stone
chips that have been touched up and other very small blemishes
that were too faint to be picked up by the
camera, but nothing that is really noticeable from about five or
ten feet away. There are NO RUST ISSUES with this car and as one
can see in the many photos of the underside it is very clean
underneath. 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 or "birdcage" area, which are
the two most notorious areas for rust on a Corvette of this era.
The car looks just as good in person as it does
in the photos.
Window Date Codes
note that almost of the glass on this Corvette, even the
windshield, is date coded and original as each piece
predates the car's body build date of May 17, 1978
(I17). Original glass is a good indication that this car
has had no major accident history and never sustained
Oyster leather interior of the Corvette is in great original
condition. The seats look in person just as they do in the
photos with a small amount of expected wear for the age.
Please note that these appear to be the original seats and
skins, not some cheap aftermarket covers or replacements. The carpet is also in
excellent condition with no rips or holes. This included
the rear carpet, which is often neglected. The
console and dash are in good condition with no fading,
cracks, or sun
damage. The original door panels are in nice shape overall. The door pulls are solid and intact. This car has
not been smoked in and there no aroma of cigarettes whatsoever. The jack
and jack handle are still present with the car and stowed
correctly behind the passenger seat, pictured below showing
the original stickers on the compartment lid. The original
spare is also still with the car. Corvette interiors from
this era are not known to
wear well and the nice condition of this interior is a huge testament to the meticulous care
this car has received throughout its life and another great
verification of the low mileage.
looks just as good in person as it does in the photos.
Corvette is in great mechanical condition and it is ready to be
enjoyed. 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. There is no
blue smoke when starting or driving the car. The brakes are
responsive and do not pull to one side or the other. The transmission shifts
smoothly throughout the power band. This Corvette has plenty of
power and is quite fast. Also, the engine compartment is
beautifully clean, detailed, and correct as one can see in the
photos, even the original ignition shielding and catalytic
converter are still in place.
The wipers work as do all
the exterior lights, interior lights, turn signals, indicators,
and rear defogger. The entire vacuum system for the headlights
works. Also, the headlights go up correctly with either the
headlight switch on the dash or vacuum override switch. Their
complete operation from both switches can be observed in the
video. All of the gauges work with the obvious exception of the
clock. The blower for the heater and a/c on all speeds but high.
The a/c on this Corvette worked fine when we received it, but
does not blow cold now so it probably needs some Freon added. One can observe
the a/c compressor clicking on and engaging properly in the
video below. The horn does not work and there is very slight
sound of an exhaust leak on the right side. 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 as well as it looks.
Overall, this 1978 Corvette is in
great driver condition. Numbers matching is extremely
important in Corvette pricing, especially with a low
mileage car like this. The originality, the rare and
desirable 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 taken care of by
its previous owners. There is a key for the ignition and
no key for the doors. We can provide a door key for the
new owner for an additional $100. The prices of C3 Corvettes have
increased drastically 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
