1977 Pontiac Bonneville Brougham Description

This is a >RARE< 1977 Pontiac Bonneville Brougham Landau Rally Coupe looking for a home with a serious collector. It is in near-new condition. I purchased this car 11 years ago when I lived in Cheyenne, WY from an estate vehicle broker. I am the second owner. The original owner special-ordered this car from General Motors with the Rally package and kept it in a garage.
The Rally Package consists of a certified 120 MPH speedometer, full gauge cluster, AM/FM/Stereo Cassette w/digital clock, and upgraded underhood accessories (intake snorkel, chrome air filter bolt, Pontiac name emblazoned on the radiator cowling, etc).
I have kept this vehicle in my garage, save driving it in parades and shows. The interior is pristine and still smells brand new. All accessories work. The vehicle starts/runs/drives perfectly. The previous owner retained all brochures, manuals, engine order specs, and even the window sticker (see photos). The vehicle also includes the spare brougham litter bin, factory carpet swatch for spot repairs, and spare door trim kits. I have both sets of original keys.
This car is 100% stock original. It is as it came from the factory 42 years ago. The only equipment replaced was the exhaust system (by the broker) as required to pass emissions. The vehicle has 40,202 original miles. This vehicle has NO rust. The vehicle has never been in an accident.
The driveline consists of an Olds-built 403 6.6L V-8 and a THM-350 3-Speed automatic transmission. I have only driven this car 4,500 miles in the past 11 years. Nevertheless, I have changed the oil/filter every six months, flushed the coolant every 2 years, and flushed the transmission fluid at 40,000 as recommended by the manufacturer. I replaced the spark plugs at 40,000 as well.
The following minor issues exist: The A/C needs a Freon recharge. (I was quoted $460 to convert to R134a and recharge the system - it was leak-checked and is ok.) The system is still under proper pressure. I did not do this because I did not want to convert the R-12 system to R-134A - I kept it original. There is a small ding on the lower-right of the driver's door. The vinyl top is showing stretch cracks due to age and the chrome flashing around the Landau windows need replacement. There are small rock pits on the nose of the hood and just above the windshield. Everything else is in excellent shape. The photos show all.
Don't miss out on this chance to own a piece of Detroit history! The successful bidder must be prepared to pay cash (no checks/money orders of any type accepted!) and drive the vehicle away, or arrange for shipment. I will accept a wire transfer for out-of-town buyers. Please contact me with any questions or concerns.
NOTES:

*FRONT GRILLE DESIGN*The front grille and bumper vents are of 1978 design. The original owner hated the 1977 style grille and had the dealership replace it with a new one from the 1978 model year. The ORIGINAL 1977 grille and vents were placed in the parts box the replacement grille and vents came in and remained with the car (see photos) should you wish to return it to the original model year style.
*CLARIFICATION REGARDING HIGH-ALTITUDE EMISSIONS*
This car was ordered and sold in the Rocky Mountain Region. It is not uncommon for vehicles to be driven up to 12,000 ft above sea level here, as anybody who has been to Denver can tell you.
Carbureted vehicles (which this one is) that are designed to run at low altitude (generally below 4,000 ft) often struggle at higher altitudes because the atmospheric air is much less dense. This causes a low altitude car to run "too rich," leading to poor fuel economy, less power, hotter operation, and more pollution.
To compensate for this, a high-altitude vehicle (like this one) generally has a larger engine with a wider throat in the throttle body of the carb. This allows more air to be drawn into the engine per stroke. The ignition timing is also advanced slightly to aide in a more complete combustion of the charge.
While a low altitude car would struggle at high altitude somewhat, a high altitude car would operate just fine at sea level. In fact, you might notice quite a bit more power during acceleration compared to a low altitude car with the same-size engine. However, the charge is leaner. If the vehicle pings or knocks at lower altitude, the ignition timing should be retarded a couple of degrees before factory specs. If you wish to leave the timing set to factory spec, try using a higher octane gasoline.
Any further questions regarding this should be directed to a mechanic for further clarification.

I drove this car to Santa Monica, CA (which is at sea level) four years ago for a classic auto show. I experienced NO ISSUES WHATSOEVER while doing so.
