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

The 1973 Corvette was truly the end of an era. 1973 was the last year to feature a chrome bumper and is considered by some to be the last year of truly classic Corvettes. Model years after were more at the mercy of insurance companies, fuel prices, and emission concerns, 1973 is considered the last "good" year by many enthusiasts. The 1973 model year is also considered a special and different year for Corvette enthusiasts as it was the only model to have chrome in the back and a rubber bumper in the front. It is representative of the transition Corvette was making at the time. As in investment, the 1973 will always have an advantage and out perform other years because of its precedence as the end of a a very great period for Corvette and muscle cars as a whole.

Exterior

The Blue-Green exterior is in nice driver condition. As one can see in the photos, the finish has dazzling gloss, deep shine, and smooth finish. The wheels and center caps are in excellent condition with a brilliant finish and no curb rash. The Goodyear Eagle GTII tires have plenty of tread left and are correctly sized 225/70R15. The chrome and other brightwork looks great with a clear finish and no pitting. There are no major imperfections that have been intentionally excluded from the photos. There is some light checking and other tiny blemishes around car that were too small to show up in pictures, but nothing that is really noticeable from about five or ten feet away. As one can see in the many photos and video of the underside this car is very clean underneath and has NO RUST ISSUES at all. The frame is totally solid around the "key hole" area in front of the rear tire and we have seen no evident of corrosion around the windshield or “birdcage” area, which are the most common spots for rust on a C3 Corvette. We have included specific photos of the areas most prone to rust to show how nice this car looks.

Window Date Codes

Please note that almost of the glass on this Corvette, both "Astro Ventilation" door windows and even the windshield, are all date coded and original as each piece predates the car's body build date of February 7, 1973 (G07). Original glass is a good indication that this car has had no major accident history and never sustained significant damage. There is a small chip in the windshield, but we decided to not replace it to keep the car as original as possible. We have the windshield replaced for an additional $300.

Interior

The Saddle interior of the Corvette is in outstanding condition. The seats look just as good in person as they do in the photos with no punctures, split seams or excessive wear. There is just a small amount of expected wear in the typical spot on the driver's bolster. The carpet is also in great condition with no rips or holes. This includes the rear carpet, which is often neglected. The gauge faces are clean and crisp. The dash is in great shape with no cracks, fading, or sun damage. The door panels are in good condition overall with some normal wear in the typical area where someone's elbow would rest. The jack and jack handle are still with the car and stored behind the passenger seat. The spare is also 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 interior is a huge testament to the meticulous care and attention this car has received throughout its life and another great verification of the very low original mileage. The interior looks just as good in person as it does in the photos.

Mechanical

This Corvette seems to be in very good mechanical condition. The original numbers matching LS4 big block engine starts right away every time, runs well, and idles smooth. This Stingray 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 or the other. The transmission shifts well, 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 photos.

The radio works as do all the exterior lights, interior lights, dash lights, wipers, and indicators; even the key buzzer still works. The a/c works and one can see the a/c compressor turning on and engaging properly in the video. The blower for the heater and a/c works on all speeds. The entire vacuum system for the headlights works correctly from both of the respective switches on the dash and the override switch under the column. The entire operation from both switches can be viewed in the video. All of the gauges work with the obvious exception of the clock. Not enough can be said as to how much of a pleasure it is to drive this car, especially with the 4-speed transmission and the extra power from the LS4 and the T-Tops out on a beautiful day.

Overall Condition



Overall, this 1973 LS4 big black Corvette Stingray looks fantastic and is in terrific driver condition. The beautiful original color combination, the 454ci engine with manual transmission, and the great extent to which the numbers match make this Stingray especially important and very hard to duplicate. Numbers matching is extremely important in Corvette pricing, especially for rare and high performance examples like this Corvette, and as one can see, this car is quite correct. There are photos of the VIN stamp on the engine block, suffix code, engine assembly date, transmission date, and transmission VIN stamp. The LS4 engine draws a great premium over the standard Corvette. This Stingray is a solid investment 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.
