Many thanks to Kristian Stoerli of Bar Italia Classics for the improved appearance!  Rust areas on the lower doors, front fenders and elsewhere were cut out and replaced with sheet metal.  Faded paint was stripped and entire car repainted in the original Brown Metallizzato between April-August 2020.

"The third generation of the Maserati Quattroporte (Tipo AM 330) was developed under the Alejandro de Tomaso-GEPI ownership...the third generation went back to the classic formula of rear-wheel drive and a large Maserati V8 engine (4930cc/280hp 4x2bbl Weber carbs). The exterior design was penned by Giorgetto Giugiaro."

"The Quattroporte III marked the last of the hand-built Italian cars; all exterior joints and seams were filled to give a seamless appearance."

History of the 1979-1990 Maserati Quattroporte III

(from the Hagerty Valuation Guide)

Maserati revived the Quattroporte name at the 1977 Turin auto show with a radically new Quattroporte III. Unlike the Citroen-based Quattroporte II of the mid-1970s, the stately Quattroporte III sedan carried attractive bodywork by Giugiaro and Italdesign, had an absolutely opulent interior that featured loosely tucked leather throughout, and used a powerful motor to drive the car's rear wheels.

Production of the Quattroporte III began in 1979 with a 255-hp, four-cam, 4.2-liter V-8, with a 280-hp 4.9-liter version of this motor being available shortly thereafter. These engines sent their power to the rear wheels through either a ZF five-speed transmission, or a Borg Warner automatic that quickly gave way to a Chrysler Torqueflite box early in production. Otherwise, the Quattroporte III saw minimal changes throughout its 11-year production run, and by 1990 just over 2,100 examples of this imposing, 140-mph executive express were produced. Most of the models had been made by 1987, with approximately 55 revised "Royale" versions completed thereafter. A few examples of a stretched limousine version were built as well.

When searching for a Maserati Quattroporte III today, buyers should remember that the models are complex cars that sell at a relatively low price, with rust and electrical gremlins being the two areas that can swallow up cash very quickly. If a QPorte is needy in these two areas, an owner can easily surpass the value of the car in repair and restoration bills--examples such as this are better off as parts cars. The suspension can wear quickly as well, however replacement pieces are readily available with Pantera front suspension parts being an exact match for most of the front suspension. With this in mind, healthy Maserati Quattroporte IIIs are powerful, imposing, and comfortable four-door touring cars. The model also enjoys a vibrant online support network that is rabidly enthusiastic about this Italian exotic that exists in a class of one.

#1 vehicles are the best in the world. The visual image is of the best vehicle, in the right colors, driving onto the lawn at the finest concours. Perfectly clean, the vehicle has been groomed down to the tire treads. Painted and chromed surfaces are mirror-like. Dust and dirt are banned, and materials used are correct and superbly fitted. The one word description for #1 vehicles is "concours."

#2 vehicles could win a local or regional show. They can be former #1 vehicles that have been driven or have aged. Seasoned observers will have to look closely for flaws, but will be able to find some not seen by the general public. The paint, chrome, glass and finishes will all appear as excellent. No excessive smoke will be seen on startup, no unusual noises will emanate from the engine. The vehicle will drive as a new vehicle of its era would. The one word description for #2 vehicles is "excellent."
