Should You Buy the 1987 BMW 5 Series?
The 1987 BMW 5 Series (E28) remains a highly engaging classic for enthusiasts, offering robust mechanics and a solid chassis. However, its age means that deferred maintenance, aging electrical systems, and the ubiquitous threat of rust pose significant ownership challenges. It's a rewarding vehicle for those prepared for its specific demands, but not a 'set it and forget it' daily driver.
The 1987 BMW 5 Series is a fantastic classic for the right owner, but it is not for the faint of heart or those on a strict budget. Be prepared for significant age-related maintenance and repairs. A thorough pre-purchase inspection is non-negotiable, and a clear understanding of its common failure points is essentia…
Best Model Years
1987-1988 (late E28s had some refinements, M30 engine in 535i is generally preferred for power and robustness).
Years to Avoid
No specific years to outright avoid within the E28 generation; condition and maintenance history are paramount over specific year.
Biggest Strengths
- Excellent build quality and robust chassis
- Generally strong and durable inline-6 engines (M20/M30)
- Rewarding driving dynamics for its era
Top Risk Areas
The systems that tend to fail first on the 1987 BMW 5 Series, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
Wiring harnesses become brittle, ground points corrode, and components like the instrument cluster's SI board batteries leak, causing erratic gauge readings, non-functional OBCs, and intermittent electrical faults.
Plastic and rubber components (radiator, expansion tank, hoses, water pump housing) degrade with heat cycles, leading to leaks, overheating, and potential head gasket failure if neglected.
All rubber bushings (control arms, sway bars, subframe) and ball joints will be worn or deteriorated, leading to vague steering, clunking noises, and compromised handling. Power steering pumps and hoses frequently leak.
1987 BMW 5 Series Mileage Danger Zones
The mileage windows when the 1987 BMW 5 Series most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Infancy Check
At this mileage, an E28 would have been relatively new. Any issues typically revolved around minor initial manufacturing flaws or early wear on consumables that are not relevant today.
Critical Maintenance Zone
This mileage signifies the point where critical preventative maintenance, like the M20 timing belt and water pump, would have been due. Neglect here could lead to major engine issues.
Aging Component Zone
Components across the vehicle start showing significant wear, requiring proactive replacement to maintain reliability and performance. Electrical issues become more prevalent.
Major Overhaul Threshold
Vehicles at this mileage will almost certainly need comprehensive overhauls of multiple systems. Expect to address head gaskets, transmission wear, rust remediation, and extensive electrical and chassis work.
1987 BMW 5 Series Ownership Cost Outlook
What it typically costs to keep the 1987 BMW 5 Series on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.
Annual Maintenance
$800-1,500 (for a well-maintained example)
Moderate Repairs
$1,000-3,000 occasionally (suspension refresh, cooling system overhaul, electrical diagnosis)
How Long Does the 1987 BMW 5 Series Last?
Focus on comprehensive maintenance records, not just low mileage. A well-maintained 150,000-mile example is often a safer bet than a low-mileage car with extensive deferred maintenance.
