Is the 1987 Porsche 911 reliable?

Yes—when maintained on schedule, the 1987 911 Carrera is considered one of the more durable classic 911s, but reliability depends heavily on service history, leak-down numbers, and whether major age-related items have been addressed.

What are the most common 1987 Porsche 911 problems?

Frequently reported issues include valve guide wear (leading to oil consumption), oil leaks from aging seals and gaskets, 915 transmission synchro wear and tired shifter bushings, and electrical/HVAC aging such as alternator regulators and weak A/C.

Are maintenance costs high for a 1987 Porsche 911?

Maintenance is typically higher than for mainstream cars because parts quality, oil capacity, and specialist labor add up; however, predictable preventive service is usually cheaper than catching up on years of neglected work.

What are the best years to buy for a classic 3.2 Carrera 911?

Many shoppers target the 1984–1989 3.2 Carrera range for its blend of performance and support; within that group, the “best” year often comes down to condition and documentation more than the calendar year.

What should I check before buying a 1987 Porsche 911?

Verify complete service records, get a professional pre-purchase inspection with compression and leak-down tests, inspect for oil leaks and broken head studs, evaluate 915 shifting quality, and confirm suspension/brake condition and electrical function. For deeper ownership confidence, get a complete owner’s guide with full specs, factory-correct capacities, and maintenance schedules tailored to the 1987 Porsche 911.
