vehicle description

 

 

Seven Hills Motorcars is very proud to offer this beautiful 1975 Corvette Convertible in excellent condition and with only 60,260 original miles. This Corvette looks terrific, runs great, and is an excellent driver. The Steel Blue (27) over Black (19V) is a very rare and beautiful color combination that looks great on the car. It is also the correct and original color combination as verified by the codes on the trim tag, which is pictured below. This is particularly important on this car as Steel Blue was a one year only color only available in 1975 and it is the most rare color with only 1,268 units made.

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, video, list of numbers, and other information below to get a true sense of how nice, clean, and original 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.

 

model description
 


1975 was a very special year for Corvette, it was the last year of the C3 body style in which a convertible model was offered. Only 4,629 convertibles were made that year, which is why the 1975 Corvette Convertible is one of the most desirable models in the entire production run of C3 Corvettes. 1975 was also the first year Corvettes featured High Energy Ignition (HEI) with no mechanical points; a dramatic improvement over previous designs.

numbers

 


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.

 
item number description*
VIN 1Z67J5S417225 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, 4, correct for an L82 car.  The sixth digit, "9," indicates the model year, 1979.  The "S" is the plant where the car was produced, St. Louis.  The last five digits are a sequence number so this is the 14,919th Corvette made for 1979.
Body Build Date F03 "F" corresponds to December, and "03" is the third day of the month meaning this Corvette's body build date is February 3, 1975.
Engine Code V0220 "V" means the engine was build in the Flint, MI plant.  The "02" is the second month of year and the "20" is the twelfth day of the month meaning the engine was assembled on February 20, 1975.  This is correct as it precedes the build date of the car.
Suffix Code CHB This means the motor was intended for an L48 Corvette with an automatic transmission, which is correct for this car.
Engine Block Casting Number 3970010 The engine block has the correct 3970010 casting number.
Engine Block Casting Date K 28 4 "K" is November, "28" is the twenty-eighth day of the month, and "4" is the last digit of the calendar year so the engine block was cast on November 28, 1974.

Intake Manifold Casting Date B 18 5 "B" is February, "18" is the eighteenth day of the month, and "5" is the last digit of the calendar year so the intake manifold was cast on February 18, 1975. 
Carburetor 7045222 The carburetor has the correct stamping for a 1975 L48 Corvette with an automatic transmission. The "70" is a code used on all Rochester carbs from 1965-1975. The third digit, "4," means the carb was built in the 1970's. The fourth digit, "5," means it was built for the 1975 model year. The fifth digit, "2," indicates that it is a 4BBL carb. The sixth digit, "2," means is was built for the Chevrolet division of GM. The last digit, "2," means it was intended for use in an automatic transmission car such as this.
Carburetor Date Code 0295 The firth three digits, "029," indicate the 29th day of the year. The last digit, "5," is the year in which the carburetor was produced, 1975. So this carburetor was stamped on January 29, 1975.
Distributor 1112888 The distributor is original and correct for a 1975 L48 Corvette with a 1112888 stamping.
Distributor Date Code 5B7 The "5" is the last digit of the calendar year, the "B" denotes February, and "7" is the seventh day of the month meaning the distributor was made on February 7, 1975. This is correct as it predates the assembly date of the engine.

Transmission Date Code 406 The assembly date code for the 1975 model year starts with the first day of the calendar year in 1974 and continues through the calendar year in 1975. This means "406" is the 406th day starting with January 1, 1974, which indicates the transmission is dated February 10, 1975.
Transmission VIN Stamping 417225 The last 6 digits of the car's VIN, 417225, are stamped on the main case of the transmission and pictured below meaning this engine is original to this car.

Starter Date Code 5B5 The first "5" is the last digit of the calendar year, the "B" denotes February, and the second "5" is the fifth day of the month meaning the starter was made on February 5, 1975. This is correct as it predates the assembly date of the engine.
Driver's Window JL "J" is May and "L" is 1974 so this window is original, made in May of 1974.  This is correct as it predates the build date of the car.
Passenger  Window JL "J" is May and "L" is 1974 so this window is original, made in May of 1974.  This is correct as it predates the build date of the car.

condition

 
 

Exterior

The Steel Blue exterior is in nice driver condition. As one can see in the photos the finish has a nice shine. The rally wheels and center caps are in great condition with a brilliant finish and no curb rash. The tires have about 80% tread left and are correctly sized 225/70R16. The convertible top operates well and goes up and down easily. It is in good condition with no holes; it does show some wear and has some fraying on the edges as one can see in the photos. The rear window is perfectly clear with no fogging or yellowing. As one would expect from a paintjob with this many years on it there are some blemishes and checking around car and on the rear decklid that were too tiny to show up in pictures, but nothing else that is really noticeable from about ten feet away. We have included many photos of the underside to show how it looks.


Interior

The Black interior in this Corvette is in spectacular original condition. The seats are in excellent condition with no excessive wear, just some small marks 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. The dash and console look awesome with no sun fading. The carpet looks good with no stains, there is a small spot in the driver's foot-well. As one can see in the photos it is not very noticeable. 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. 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 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.


Mechanical

This Corvette seems to be in very good mechanical condition. The car starts right away every time, runs well, and idle 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 65mph, 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 transmission shifts smoothly. 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 exceptionally clean, beautifully detailed, correct and complete as one can see in the photos.

The original stereo radio works as do all the exterior lights, horn, wipers, power windows, and all of the gauges with the obvious exception of the clock. The blower works on all speeds and the a/c also works and blows cold. One can observe the a/c compressor clicking on and engaging properly in the video. The vacuum system for the headlights works correctly. Also, the headlights go up properly with either the headlight switch or vacuum override switch. There complete operation form both switches can be viewed in the video below. The catalytic converter has been removed and the car now has true dual exhaust with a very healthy tone. As with many older carbureted cars it is cold blooded and runs best when it is warmed up. The heater core has been bypassed. Not enough can be said as to how much of a pleasure it is to drive this car, especially with the top down on a beautiful day.


Overall Condition

Overall, this 1975 Corvette Convertible is in wonderful driver condition. The convertible models always draw a great premium over the coupes and 1975 has always been a special year as it was the last C3 drop top. The original owners manual is still with the car. Matching numbers is very important in Corvette pricing and as one can see this Stingray is very correct. The originality, the very low miles, the beautiful and rare original color combination, and the great overall condition 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. 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.
