Seven Hills Motorcars is very proud to offer this absolutely
spectacular 1970 L46 350ci 350hp Corvette Convertible in stunning
condition with the Muncie M21 Close Ratio 4-Speed and both hard and
soft tops. The Stingray has very low original mileage, is completely
numbers matching, and exceptionally clean. This Corvette looks
great, runs awesome, and is a magnificent driver that feels great
out on the road. It is finished in the beautiful and highly
desirable color combination of Mulsanne Blue over Blue Vinyl.
This is the correct and original color scheme as verified by
the codes on the trim tag. We have put over 40 miles on the car and
in that time it ran great, was a pleasure to drive, and was
We have the car priced to sell and are offering an excellent
opportunity to own a very desirable Corvette 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 C3 "chrome bumper" Corvettes from 1968 to 1972 is
absolutely red hot right now and on the rise. The 1970 model
year Corvette was only made for 6 months and is the most
rare of the "chrome bumper" years. There is no way someone
could buy a similar Corvette and restore it to this level of
quality for anything near our asking price. The low original
mileage is verified not only by the condition of the car,
but also the clear Ohio title that is pictured below showing
the mileage as "Actual." Please peruse all of the photos,
video, numbers, and other information below to get a true
sense of how nice 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.
1970 was the last year for high compression, truly full output, and
all out performance engines in Corvettes. The model years to follow
were more at the mercy of insurance companies, fuel prices, and
emission concerns. The 1970 Corvette saw the shortest production
time and lowest production numbers for any year of "chrome bumper"
Corvettes. Total production in 1970 was only 17,316, which was the
lowest since 1962. A strike at GM caused the 1969 model year to run
for an extra 4 months so production on the 1970 models did not start
until January of 1970. The body shape in 1970 was improved with
fender flares to reduce the damage from wheel thrown debris. Many
enthusiasts prefer the more pronounced fender flare and wheel
opening introduced this year. 1970 also introduced the iconic
"egg-crate" grills on the side of the car, which were only used on
Corvettes for 3 years and have become a symbol of the "chrome
bumper" Corvettes. The interior saw subtle improvements including a
redesigned seat for better headroom and better access to the storage
area. As in investment, the 1970 model year be particularly great
due to the rarity and the fact that this was the last year Corvettes
and muscle cars as a whole were purpose built for speed and
performance without the limitations from environmental and emission
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 correctly.

and Mike Antonick's Corvette Black Book.
Blue exterior is in brilliant condition. As one can see in the
photos the finish has a dazzling gloss, smooth finish, and deep
shine. The body is straight and both doors open and shut nicely.
The chrome bumpers show very well overall. The wheels and center
caps are in excellent condition with a nice finish. Please note
that these are the correct and original style 4-clip beauty
rings, not the cheaper aftermarket replacements. The BF Goodrich
Radial TA tires are correctly sized 225/70R15. The soft-top is
in nice shape and the rear window is not yellowed or foggy. The
top itself operates well and opens and closes easily, and needs
a latch. Often Corvettes will have particularly chipped up front
ends, this car does not. There are a couple very small nicks
that have been touched up around the car that were too tiny to
show up in photos and on spot near the antenna, but nothing that
is really noticeable from about five feet away. As one can see
in the many photos of the underside, this Corvette is very clean
underneath and totally solid with absolutely no rust issues.
There is no rust around the "key hole" area of the frame in
front of the rear tires and no evidence of corrosion around the
windshield or "birdcage," the most common areas for rust on C3
Corvettes. We have included many photos of the underside to show
how great it looks.
note that this Stingray also come with the body colored
hardtop. This adds value and is a great benefit to any
This Corvette looks as good in person as it does in the
Window Date Codes
Please note that almost
all of the glass on this Stingray, both of the the "Astro
Ventilation" door glass and even the hardtop rear
window, is date coded and original as each piece
predates the car's body build date of May 13, 1970
(E13). Original glass is a good indication that this car
has had no major accident history
and never sustained significant damage.
The Blue Vinyl interior in this Corvette is in outstanding
original condition. The seats are in excellent condition
with no split seams or excessive wear. They are not worn in
the typical area where the driver gets in and out. Please
note that these appear to be the original seats and skins,
not some cheap aftermarket covers or replacements. They do
have the typical dry foam and there is one spot on the left
side of the right seat, but as one can see in the photos it
is not very noticeable. The carpet is also in fantastic
condition with no major stains or holes. This includes the
rear carpet, which is often neglected. The door panels are
in wonderful shape with no splits or cracks. The door pulls
are solid and intact. The dash and console look awesome with
no cracks or sun fading. The radio in the car get great
reception and is a Corvette specific unit made to fit this
car so most importantly the original dash was never cut or
modified for the installation. The jack and jack handle are
still with the car, stored correctly behind the passenger
seat, and pictured below showing the original decals on the
compartment lid. The spare is still with the car as well.
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 mostly original 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 interior looks as good in person as it does in the
This Corvette seems to be in very good mechanical condition. It
starts right away every time, idles well, and runs great. The
car is a awesome driver that feels nice the road and at highway
speeds. As stated above, we have put over 40 miles on the car
with no issues at all. 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 it drives smooth and the car
performs quite well overall. It runs cool and does not overheat.
The brakes are responsive and do not pull to one side or the
other. The shifter is tight, the transmission does not pop out
of gear, and the clutch feels good. Also, the engine compartment
is beautifully clean, detailed, and correct as one can see in
The horn works as do all the indicators, wipers, and
exterior lights. The entire vacuum system for the
headlights and wiper door works correctly from both
their respective switches on the dash and the override
switches. The entire operation from both switches can be
viewed in the video below. The dash lights work as one
can see in the video. One can also see that the
"Seat-Belt," "Door Ajar," and even the "Head Lamps"
lights on the dash all work correctly. All of the gauges
work with the obvious exception of the clock. Some of
the fiber optics work. The blower for the heater works
on all speeds. Not enough can be said as to how much of
a pleasure it is to drive this car, especially with the
4-Speed, the extra power fro the L46, and the top down
on a beautiful day.
on the fiber optic light monitoring system. We
consistently receive many questions about the purpose of
this system; exactly what it is and what it does. The
sole and main idea behind the fiber optic light
monitoring system is to simply confirm that all of the
exterior lights, headlights, indicators, tail lights,
etc., are working and to make the driver aware of a a
burned out bulb. Each lamp on the outside of the car has
an actual fiber optic cable the runs to an indicator on
the center console. There are nine small indicators on
the console and each has its own finer optic cable. When
the bulb goes on the light travels through the fiber
optic cable and illuminates the corresponding indicator
on the console. If someone does not remember to plug the
cable end into the lamp housing, does any work to the
center console, or if there is a break in a connection
or anywhere along the cable, that indicator no longer
works. As one can image, over time this is very common.
Overall, this 1970 Corvette is in
exceptional driver condition and truly and investment
grade car. The higher horsepower models like the L46
always draw a great premium over the standard base
350ci. In my opinion and based on our experience the
"Chrome Bumper" cars from 1968-1972 are the most
collectible and hottest in the entire Corvette market
right now and 1970 is particularly desirable due to its
rarity. The excellent condition, the great extent to
which the numbers match, and the beautiful color
combination make this car especially important and
difficult to duplicate. 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 prices of C3 Corvettes have
increased drastically over the past 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.
