1977 Cadillac Eldorado

1977 Cadillac Eldorado Hardtop For Sale

30,111 Original Miles Numbers-Matching 425 V8 Madeira Maroon Three Meticulous Owners Purchased From Seven Hills Motorcars at 28,150 Miles Exceptional Originality

This 1977 Cadillac Eldorado is an exceptionally well-preserved, low-mileage example showing just 30,111 original miles and benefiting from a remarkably well-documented history of careful ownership, preservation, and conscientious maintenance.

Finished in its factory-correct Madeira Maroon, Code 79, over a beautiful Claret Edinburgh Cloth and Antique Coated Fabric interior, Trim Code 79B, with a matching vinyl roof, this Eldorado retains an impressive amount of original equipment, trim, documentation, and period character.

The Fisher Body tag further identifies AV7 Dual Comfort 50/50 seating and a 10B build date, representing the second week of October 1976.

The current owner purchased the Cadillac from Seven Hills Motorcars with 28,150 original miles. At that time, Seven Hills documented the car as an exceptionally original survivor with its numbers-matching drivetrain, original sheet metal, date-coded glass, outstanding interior, and remarkably solid underside. Seven Hills also reported driving the Cadillac approximately 50 miles during its ownership without problems and described it as reliable and enjoyable to drive.

Since taking delivery, the current owner has added fewer than 2,000 miles while completing an extensive program of mechanical, electrical, suspension, HVAC, cosmetic, and convenience-system servicing.

Three Meticulous Owners

This Eldorado has had only three careful owners.

The current owner is a retired CPA, Cadillac club member, and regular participant in car shows who is exceptionally particular about how the car is maintained.

Whenever service or replacement has been necessary, he has made a conscious effort to locate NOS, OEM, rebuilt-original, or correct authentic replacement components whenever possible rather than simply installing whatever aftermarket part was easiest to obtain.

That philosophy can be seen throughout the car, from the NOS radiator and rebuilt original Quadrajet to the repaired factory radio, rebuilt original clock, OEM power antenna, correct radiator hose and clamps, preserved original speaker covers, and surviving trunk equipment.

This has been a preservation-first ownership experience rather than an attempt to modernize or reinvent the car.

VIN & Factory Identification

VIN:

6L47S7Q131448

The VIN identifies this as a 1977 Cadillac Eldorado two-door coupe, factory equipped with Cadillacs carbureted 425 cubic-inch V8 and assembled in Detroit.

The Fisher Body tag confirms:

1977 Cadillac Eldorado Coupe
Madeira Maroon - Paint Code 79
Claret Edinburgh Cloth & Antique Coated Fabric - Trim 79B
AV7 Dual Comfort 50/50 Seating
10B - Second Week of October 1976 Body Build

The combination of VIN information, body-tag data, numbers-matching drivetrain, original glass, preserved interior, and surviving factory equipment gives this Eldorado an unusually complete identity.

Numbers-Matching 425 V8 & Transmission

Under the hood is the cars original 425 cubic-inch Cadillac V8, backed by its original automatic transmission and Cadillacs front-wheel-drive system.

Both major drivetrain components have been documented as numbers matching.

The final six digits of the VIN - 131448 - are stamped on both the engine block and transmission case, confirming that both units are original to the car. Seven Hills photographed and documented these stampings when the car was offered for sale.

Seven Hills also reported that the engine started easily, idled smoothly, ran cool, and displayed no abnormal smoke, noises, or vibrations. The transmission shifted properly, and the car was road-tested at highway speeds.

Since then, the current owner has addressed numerous mechanical items proactively, making the Cadillac considerably more sorted today.

Purchased From Seven Hills Motorcars

The Seven Hills Motorcars listing provides an unusually valuable historical snapshot of the Cadillac at 28,150 original miles.

Seven Hills represented the Eldorado as a carefully selected vehicle rather than a dealer-auction acquisition and extensively photographed the underside, floors, rockers, lower quarters, structural areas, and other locations typically susceptible to corrosion.

At the time of sale, Seven Hills represented the body panels and sheet metal as original and described the underside as exceptionally solid.

The mileage was also supported by a clear Ohio title identifying the mileage as Actual.

That documentation provides an excellent baseline showing the cars condition before the current owner began his extensive maintenance and improvement program.

Original Date-Coded Glass

Another particularly interesting feature is the survival of the Cadillacs date-coded glass.

Seven Hills documented that all of the major glass pieces predated the cars second-week- of-October 1976 body build:

Windshield: September 1976
Drivers Door Glass: August 1976
Drivers Rear Glass: June 1976
Passenger Door Glass: August 1976
Passenger Rear Glass: June 1976
Rear Window: September 1976

The consistency of those dates provides another indication of how intact this car remained before the current ownership.

Factory Madeira Maroon Exterior

The exterior is finished in its factory-correct Madeira Maroon, Code 79, beautifully complemented by the matching vinyl roof and Cadillacs extensive chrome and brightwork.

Seven Hills specifically documented the Madeira Maroon and Claret color combination as matching the codes on the Fisher Body tag.

The body remains remarkably solid, including the floors, lower quarters, rockers, and underside.

In October 2025, localized rust affecting the lower right and left front fenders beneath the moldings was professionally repaired, and the affected portions of both panels were refinished.

This was localized corrective work rather than evidence of a generally rusty car. Seven Hills had previously documented the floors, rockers, quarters, frame areas, and underside as exceptionally clean and solid.

New Diamondback whitewall tires were installed in January 2025, retaining the proper period appearance while improving drivability and road manners.

Outstanding Original Claret Interior

The interior is one of the strongest aspects of the entire Cadillac.

Trim Code 79B identifies the factory upholstery as Claret Edinburgh Cloth and Antique Coated Fabric, while the AV7 designation identifies Cadillacs Dual Comfort 50/50 front seating.

The seating surfaces appear to remain original and show remarkably little wear.

Seven Hills specifically noted the absence of excessive seat wear, split seams, dashboard cracking, fading, and sun damage. They also documented the excellent condition of the carpeting, original floor mats, gauges, brightwork, door panels, and drivers armrest.

The car has also been represented as a nonsmoker example.

Factory comfort and convenience equipment includes:

Six-way power front seating
Power windows
Power door locks
Automatic climate control
Air conditioning
Cruise control
Power antenna
Rear-window defogger
Remote trunk release
Automatic trunk pulldown
Map and courtesy lighting
Illuminated-entry system

A particularly interesting feature is the illuminated-entry system, including lights beneath the exterior door handles - exactly the sort of small luxury touch Cadillac was famous for during this era.

A new passenger-side courtesy-light assembly has also been installed.

One currently noted item is that the passenger-side power door lock does not operate properly.

Original Radio, Rebuilt Clock & Speaker Improvements

When Seven Hills sold the Cadillac, it was equipped with a vintage-style Custom Autosound radio while the original Cadillac radio was included separately with the car.

The current owner went a step further.

The original Cadillac radio was professionally repaired and reinstalled, returning the dashboard to its authentic factory appearance.

The original clock was also professionally rebuilt and reinstalled and is now functional.

New front speakers were installed, and the audio system has additionally been fitted with Kicker 6x9 speakers.

Importantly for the preservation-minded collector, the original speaker covers were retained and remain in the trunk.

A new map-light assembly has also been installed.

These improvements perfectly illustrate the approach taken throughout this car: improve functionality without discarding original components or altering the character of the Cadillac.

Climate Control & Air Conditioning

Considerable attention has been given to Cadillacs sophisticated automatic climate- control system.

When Seven Hills sold the car, the air conditioning operated and blew cold, but the blower was primarily directing air through the lower outlets.

The current owner subsequently completed extensive HVAC work including:

HVAC air-distribution repairs
Vacuum-hose repairs
Vacuum-source repairs
Rebuilt Caddy Daddy A/C programmer
Hot/cold air-door adjustment
Climate-control sensor reconnection
Air-temperature s
