Overview

The 1987 BMW 7 Series is a full-size luxury sedan from the E32 generation, positioned as BMW’s flagship for comfort, technology, and high-speed cruising. It’s ideal for drivers who want classic German road manners, a quiet highway ride, and a traditional rear-wheel-drive luxury feel. In 1987, the E32 was still relatively fresh and represented BMW’s push to compete head-to-head with the Mercedes-Benz S-Class. Today it’s best suited to enthusiasts who appreciate vintage BMW engineering and are willing to keep up with age-related maintenance.

Key Features

1) E32 platform and classic BMW dynamics: Rear-wheel drive layout with a balanced chassis and confident high-speed stability, especially on the highway. 2) Engine options (market-dependent): Many 1987 7 Series models were offered with inline-six power, commonly the 3.4L M30 (735i/735iL), while some markets also had V12 availability in the E32 range. Output varies by market and specification, but the emphasis is smooth torque and refined cruising rather than modern fuel economy. 3) Long-wheelbase availability: “iL” models add rear legroom and a more limousine-like ride, making the car more comfortable for passengers. 4) Premium comfort and convenience: Expect upscale seating, strong sound insulation, and high-end features for the era such as automatic climate control, onboard electronics, and power accessories (equipment varies by trim and market). 5) Autobahn-focused gearing and refinement: The 1987 7 Series was built as a long-distance executive sedan, with stable handling and a composed feel at speed.

Common Issues & Reliability

Owners researching “1987 BMW 7 Series problems” and “1987 BMW 7 Series reliability” should expect a solidly engineered car with typical 1980s BMW wear points, plus age-related issues from wiring, rubber, and cooling components. 1) Cooling system failures (often 80,000–150,000 miles, or sooner with old parts): Radiators can crack with age, water pumps can leak or wobble, thermostats stick, and old coolant hoses can fail suddenly. Overheating is the big risk on these engines, so cooling upkeep is critical. 2) Electrical gremlins and instrument/cluster issues (age-related, mileage varies): Common complaints include intermittent power window operation, central locking quirks, worn relays, failing capacitors in electronics, and dash/instrument issues such as flickering gauges or warning lights. These aren’t always expensive individually, but diagnosis can take time. 3) Oil leaks and gasket seepage (often 100,000+ miles): Valve cover gasket leaks are common, and older seals can seep around the front of the engine. Leaks may not be catastrophic, but they can create smoke smells, mess, and maintenance frustration if ignored. 4) Suspension and steering wear (often 90,000–140,000 miles): Control arm bushings, ball joints, tie rods, and shocks wear with time and can cause shimmy, clunks over bumps, vague steering, or uneven tire wear. A properly refreshed suspension restores the “BMW feel,” but neglected examples can drive poorly.
