1987 Porsche 911: Buy or Avoid?
The 1987 Porsche 911 Carrera 3.2 represents a robust pinnacle of air-cooled engineering, offering surprising durability for a classic performance vehicle. However, decades of ownership and potential deferred maintenance introduce moderate risks, making a thorough pre-purchase inspection absolutely critical to unlock its legendary reliability.
While inherently a robust machine, buying a 1987 Porsche 911 requires extreme vigilance. Its legendary reliability hinges entirely on decades of diligent maintenance. Only proceed if you have a thorough pre-purchase inspection by an air-cooled specialist and a clear budget for expected age-related repairs. This isn'…
Best Model Years
1987-1989 Carrera 3.2 (G50 transmission)
Years to Avoid
No specific years to outright avoid within the 3.2 Carrera run, but pre-1987 911s with the 915 transmission are often considered less desirable by some due to shifting characteristics and are more prone to synchro wear.
Biggest Strengths
- Naturally aspirated 3.2L flat-six engine is famously durable if maintained
- G50 transmission is robust and desirable
- Excellent build quality from its era, minimal major structural issues if well-kept
1987 Porsche 911 — Known Trouble Spots
The systems that tend to fail first on the 1987 Porsche 911, 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.
The 3.2L flat-six is prone to oil leaks from various points, including the engine case halves, chain tensioner covers, valve covers, and oil return tubes. These are often age-related gasket and seal failures, exacerbated by heat cycles.
Aging wiring harnesses, brittle insulation, and failing relays (especially the DME fuel pump relay) can cause intermittent starting issues, non-functioning gauges, window motor failures, and general electrical gremlins.
Rubber bushings throughout the suspension (control arms, sway bars) and steering rack boots degrade over time, leading to vague steering, excessive play, and diminished ride quality. Shocks and ball joints also wear out.
1987 Porsche 911 Mileage Danger Zones
The mileage windows when the 1987 Porsche 911 most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone
At this mileage, a 1987 911 is likely a very well-preserved example with minimal wear. Focus on verifying service records and addressing any very early signs of aging seals or electrical gremlins.
Maintenance Zone
This mileage range typically marks the need for significant fluid services, potential early suspension bushing replacement, and thorough inspection for developing oil leaks. Clutch wear might also start to become noticeable, depending on…
Elevated Risk Zone
Approaching six-figure mileage, expect significant rubber component degradation, more pronounced oil leaks, and potential electrical issues. A full suspension refresh, engine reseal, and transmission synchro inspection are often due or o…
High Risk Zone
At this point, virtually every wear item has likely reached or exceeded its design life. A comprehensive engine rebuild, transmission overhaul, and complete electrical and suspension renewal should be anticipated if not already completed.
1987 Porsche 911 Ownership Cost Outlook
What it typically costs to keep the 1987 Porsche 911 on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.
Annual Maintenance
$1,000-2,500 (for a well-maintained example, more if catching up on deferred items)
Moderate Repairs
$1,500-4,000 occasionally (e.g., oil leak repairs, suspension refresh, clutch replacement)
How Long Does the 1987 Porsche 911 Last?
Focus less on the absolute mileage and more on comprehensive service history. A high-mileage car with meticulous records and recent major services is often a safer bet than a low-mileage 'barn find' with unknown history.
