By virtue of its chassis number, it is clear that this striking SS Coupe is among the last examples built, and therefore benefits from the steady evolution of factory upgrades and changes that occurred during Ghibli production. As chassis no. 2508 is generally regarded as the final Ghibli built, and as coupes solely used even numbers, the featured car is almost certainly the penultimate example in the numbering sequence (and likely among the last few built by date). This SS therefore was equipped with such desirable features as power steering, a Bonaldi brake booster, bolt-on Campagnolo wheels, Veglia gauges, dashboard rocker switches, and a Vitaloni stalk.
According to a Maserati Classiche build record, the Ghibli SS completed assembly in late October 1971 and was unusually equipped with right-hand drive and finished in rosso fuoco paint with a white Connolly leather interior. Confirmed by Maserati Classiche to be one of only 12 Ghibli SS 4.9 Coupes constructed, chassis no. 2506 was delivered in London and first registered in the UK in November of 1971, and is believed to have remained in Great Britain since new. According to a previous registration, the car had passed through the hands of five previous owners before being purchased by Henry Alfred Abbott of Tadworth. In 1999, the car was purchased by Pragnesh Mistry of London following a full restoration and remained with him for six years before being acquired by the consignor.
As a part of his exceptional collection of Maseratis, the current owner continued to domicile the car in London. Looking to use the car as a weekend driver and occasional long-distance tourer, the Ghibli SS was soon sent to McGrath Maserati for a comprehensive mechanical and cosmetic restoration, including a fabulous refinish in the period-correct color of Verde Gemma, and re-upholstery of the interior with light brown leather. It is accompanied today by extensive service invoices from 18 years of service by McGrath Maserati with both current and previous owners.
Now offered for the first time in 15 years, this rare right-hand-drive Ghibli SS is notable as one of the final cars built, the culmination of six years of production evolution. Having been restored to factory specifications and toured extensively around continental Europe with its current owner, accumulating over 4,000 miles since its restoration. It would make an ideal entrant for regional concours d’elegance and Italian car shows or may be appreciated on the open road for the 4.9-liter engine’s smooth torque and muscular performance.
