2016 Maserati Grancabrio 4.7L Petrol · FM16 OBD

The Maserati GranCabrio presents a mixed but broadly stable roadworthiness profile as of its most recent MOT on 20 May 2025 at 11,433 miles. That test passed, yet the tester flagged multiple advisories that point to deferred cosmetic and consumable maintenance rather than acute mechanical failure. Both front and rear brake discs were worn, pitted, scored, and corroded on both sides, indicating the car has likely sat stationary for extended periods, allowing surface corrosion to develop on friction surfaces. All three tyres noted were either cracked, perished, or worn on the inner edge, and both front wiper blades were splitting. None of these items constitute a serious structural or safety-critical defect, but together they suggest a pattern of low use and sporadic upkeep rather than diligent preventative maintenance. The mileage record reinforces that interpretation. Across a decade of ownership, the car has covered just 11,433 miles, averaging roughly 1,143 miles per year. Between the July 2021 test at 11,130 miles and the August 2022 test at 11,272 miles, only 142 miles were added over thirteen months. The gap between August 2022 and May 2025 is even more striking, with the odometer reading frozen at 11,433 miles for nearly three years. Such prolonged static storage is consistent with the widespread tyre perishing and brake disc corrosion noted in the 2025 test, as tyres age and harden rather than wear from use, and brake surfaces rust without regular heat cycling. A buyer should inspect the tyres carefully, not just for remaining tread depth but for sidewall integrity and date codes, since aged rubber can fail unpredictably at speed despite appearing serviceable. The inner-edge wear on the nearside front tyre raises a question about wheel alignment or suspension geometry, so checking the condition of front suspension bushes, track rod ends, and wishbone joints is advisable. The corroded and pitted brake discs may require replacement rather than simply skimming, particularly if the pitting is deep enough to compromise structural integrity or cause uneven pad contact. Brake calipers should also be examined for seized pistons or sticking slides, common on low-mileage vehicles that sit unused. Beyond the flagged items, the underbody and subframes merit close inspection for corrosion, as long periods of inactivity in damp conditions can accelerate rust on a car of this age and value. The exhaust system, fluid levels, and coolant hoses should be checked for age-related deterioration. The record shows no recurring mechanical failures or structural defects, which is reassuring, but the cumulative picture is one of a vehicle that has been cherished more for its rarity than driven with any regularity. A thorough pre-purchase inspection by a marque specialist is strongly recommended before committing.
