1980 Maserati Quattroporte:

From Honolulu to Burbank, California

Quattroporte Background and Article References

April - May 2019

The Maserati engine compartment was detailed and the car was again (!) polished and waxed for the Burbank Kiwanis Car Show, April 28 at Johnny Carson park 

The Quattroporte had a "For Sale" sign on the dash - the first announcement of a search for a new owner!

Here's a link to a video walk-around of the Maserati at this event.

May 2018 - March 2019

Appropriate Veteran's/USMC license plates were picked up from the DMV on January 10; replacing ordinary California plates which replaced the Hawaii "Horseless Carriage" plates - "the third time is a charm"!

This webpage follows up the "recommissioning" history and planned sale of a 1980 Maserati Quattroporte III, initiated by  owner Larry Thompson over a 20-month period in his Honolulu shop.  

Here's an update of the work originally done in Honolulu and new Burbank tasks taken on by new owner Bob Schmitt:

Pending Tasks

1.  Paint and patches - The paint on all horizontal surfaces was severely weathered and sun burned.  These surfaces were sanded, smoothed with rubbing compound, polished and waxed.  This video hows the partly polished roof.  Polishing and waxing continues!  Small rust areas of the lower doors and front fenders will eventually be cut out and patched with sheet metal. Re-painting will also be considered.

2.  Interior - Leatherique Rejuvenator Oil was applied to the rear seats on August 8; Prestine Clean then removed  the excess oil and grime after a day in the sun. Grey sheepskin covers were taken off the front seats.  These seats were dirtier than the rear seats and were similarly treated with the Leatherique process on August 9.  Results are very good! All leather surfaces will be checked and re-treated as needed.


1.  Air conditioning - Larry disconnected the compressor clutch prior to shipping.  When the circuit was connected according to his directions, the A/C worked well.

2.  Gas support struts for hood and trunk - none of the four struts held up the hood or trunk.   One of each was removed and part numbers for both confirmed - Sachs SG270001 for the hood and Sachs SG270002 for the trunk.   Master Auto Parts (Sun Valley) matched the hood supports to a StrongArm part (at a good price!) and they were installed.  The trunk struts were obtained from MaseratiNet (MIE Corporation) and installed.  The trunk now responds to the console button, as designed.

3.  Rear door, passenger side - when picked up in Buena Park, this locking button could not be depressed to lock this door nor could the car be fully locked with the central locking system.  The door panel was removed to identify the cause - seemed to be a lack of lubrication on the multi-part linkage.  All linkage parts were sprayed with Kroil and the door lock operated as designed.  The door panel was left off for a few days to confirm the locking mechanism was fixed.  Update later - all  locks work well and the panel was re-installed.

4.  Window tint film - the old, wrinkled film was removed with an inexpensive travel steamer.   Ammonia cleaned up the residual glue.

5.  Leather - Larry bought a "half hide" long ago to recover the dash.  He sent the remaining leather, rolled in a tube to Burbank by UPS.  It may be useful in the future!

6.  The plain license plate frame was replaced with a University of Hawaii frame - see third photo from top, above.

7.  A used but "as-new" console cover bought from eBay replaced the worn/torn original.

8.  A window switch was bought from eBay as a spare.

9.  Chrome and other "bright work" polished.

10.  Gas gauge - Larry created an electrical bypass to show enough fuel to meet shipping requirements, as noted in his reports, the gauge was not operating.   Alfa Italia replaced the fuel sensor float, the gauge circuit was re-connected and indicated about 1/4 tank. Alfa Italia also added gas; we added more. There were probably about 11 gallons in the tank at that time.  The tank was filled and gauge was active briefly, then died!  The tank was filled again on August 11.  The gauge showed a fill level and settled down "near full" at idle but fell to zero when underway.  The gauge showed a fluctuating but mostly correct level on August 22, then went to zero on August 27 and remained inoperative.  It continued to show zero fuel until November 1; it then indicated about 1/3 full.  The tank was filled on November 3 and the gauge showed a fluctuating but mostly correct level

11.  Smog certificate - Alfa Italia checked the timing and the carbs before a smog test at the In and Out test center.  The Maserati passed on August 22.

12.  California registration - completed at AAA on August 23.

13.  Tires & wheels - Larry replaced the two front (old) Pirelli tires with Kumho Solus tires in Honolulu.  I was advised to replace the two Pirelli tires on the rear wheels.  Matching Kumho Solus tires were installed on October 12; the wheels were cleaned.

14.  The sheepskin covers that had been removed from front seats were replaced with "Kool Kooshion Faux Leather Full Seat Cushions".  These are easily removed for car shows or leather maintenance.

15.  Master Auto Parts (Sun Valley) matched and provided a pint of "Brown Metallizzato" paint (see a photo of a Quattroporte in this color). with reducer and hardener, for touch-ups on October 11.  The light brown paint on the driver's side rear quarter panel and one very small area on the rear door were sprayed, sanded and rubbed smooth on October 22.   The panel was given a second coat of paint in May, 2019.

16.  Carpets - the original insulation was hard, brittle and flaking off.  On October 24, Ensolite foam (1/8") was purchased from the Foam Mart, Burbank.  The Ensolite was glued to the four carpet sections which were reinstalled on October 28.

17.  The missing passenger-side door protection molding was replaced on November 1.

18.  A broken clip on the passenger sun visor was repaired on November 6.

19.  The Weber carburetor diaphragms were replaced at Alfa Italia, May 2019.

20.  The headliner was cleaned, May, 2019.

In summary, the Maserati runs and drives very well as a unique Italian classic.  Petrolicious agrees - "The Maserati Quattroporte is Brutally Beautiful"!

Paint rejuvenation started, in Burbank

The long Honolulu project and journey was nearly complete in May, 2018 when the Maserati arrived in Burbank!  But not "at home"; the photo below is at Alfa Italia in Burbank to cure a fuel-blockage problem, possibly caused by agitation of the gas tank during shipping.

Alfa Italia, a great Alfa Romeo specialist (and other exotic cars) in Burbank, diagnosed the "no start" problem as dirt or varnish in the fuel tank.  The tank was removed, sent for cleaning and re-installed.  I brought the car home this day - my first ever drive!

The Maserati comes home!

At Alfa Italia (below)

Shipping from Honolulu to California was arranged through Pasha Hawaii. Pasha called on May 25, 2018 to report the Maserati was available for pickup in Buena Park, but the call came too late in the day for an immediate pickup.  We made an appointment to pickup the Maserati at 9:30 am, May 30.  We traveled from Burbank to Buena Park by Metrolink and OCTA bus, expecting to drive home in the Quattroporte. After much wandering in the Buena Park industrial area, we eventually found the Pasha lot. The Maserati would not start!  AAA was called and a flatbed brought us and the car to Alfa Italia in Burbank - see photos immediately above.  Two boxes and a large tube later arrived from Larry with the owner's manual, new leather, the old fuel pumps and other non-critical parts that can be renewed.

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.
