Maserati - Biturbo ES 2.5 Coupé - 1988

GENERAL:

This offering presents a 1988 Maserati Biturbo ES Coupé 2.5 V6 Twin Intercooler, first registered in 1988. It represents one of the final carburetted "ES" export models produced before Maserati transitioned fully to fuel injection, and it features factory-equipped power steering (servosterzo) alongside full "S" specification upgrades. Delivered new to Spain, the vehicle has remained in the country throughout its life, preserving its condition in a dry climate free from road salt exposure.Historically, Alejandro de Tomaso introduced the Biturbo range in 1981 to make Maserati accessible to a broader market, pioneering the world’s first production twin-turbocharged V6 engine. The export variant "E" models (including the performance-oriented ES) utilized the enlarged 2.5-liter engine rather than the domestic Italian 2.0-liter tax-bracket unit. The introduction of twin air-to-air intercoolers addressed heat heat-soak challenges of earlier designs, boosting output to 205 HP while retaining the responsive Weber carburetors. A well-known quirk of the Biturbo generation is its sensitive interior instrument assembly; odometer failure due to brittle plastic odometer gears is a common condition across surviving 1980s Maserati models.

BODYWORK & PAINT:

The exterior features its original factory two-tone Rosso Red and Anthracite paintwork in excellent overall condition. The body shell, floorpan, chassis, underbody, and wheel arches are completely rust-free. The vehicle retains its original Maserati alloy wheels fitted with fresh tires in the factory size (185/65 R14) showing less than 500 km of use.

TECHNICAL:

Power is generated by a 2.5-liter V6 equipped with Weber carburetors and twin IHI turbochargers featuring an original Twin Intercooler setup delivering 205 HP. The engine pairs with a manual ZF dogleg gearbox. The steering system features rare factory power steering (servosterzo). Suspension upgrades consist of Koni Red front shock absorbers and Bilstein Yellow rear shock absorbers. Engine cooling is enhanced by an upgraded high-performance aluminum radiator while retaining factory aesthetics. Recent fluid maintenance performed by a classic car specialist includes fresh engine oil, transmission fluid, differential fluid, and brake fluid. The vehicle starts immediately and runs smoothly.

INTERIOR:

The cabin preserves its high level of originality and includes the factory original radio. The instrument cluster displays an odometer reading of 75,230 km. The odometer gear mechanism has stopped functioning—a widespread physical wear issue on these instrument clusters—and has intentionally been left unaddressed to preserve odometer assembly provenance. True mileage is documented separately via inspection records.

DOCUMENTS:

The vehicle comes with an extensive documentation portfolio, including the original owner's handbook, original service booklet, original Maserati leather document pouch, two sets of keys, maintenance and repair receipts, and full Spanish ITV inspection certificates spanning from 2012 to 2024 confirming progressive mileage records. Official Spanish DGT Historic Vehicle certification is included alongside original spare parts, including the full-size spare wheel with factory tool kit, original radio blanking plate, and original seat upholstery accessories.

COLLECTION:

The vehicle is located in A Coruña, Spain. Worldwide shipping can be organized upon request, and independent professional pre-purchase inspections are welcomed.

OTHER INFORMATION:

Having achieved official Historic Vehicle registration status in Spain, the car enjoys statutory exemption from annual road tax (IVTM) and holds unrestricted access rights to urban Low Emission Zones (ZBE) under current Spanish environmental laws.
