Is the 1987 Mazda RX-7 Worth Buying?
Owning a 1987 Mazda RX-7 is a passionate affair, not a practical one. This vehicle demands a dedicated owner who understands the unique care and potential financial commitment of its legendary rotary engine. While its handling and styling are timeless, a decision to buy must be tempered with a clear understanding of the significant maintenance and rebuild risks involved.
The 1987 Mazda RX-7 is a car for the dedicated enthusiast or collector, not for the casual buyer seeking reliable transportation. It offers an undeniably engaging driving experience and iconic styling, but it comes with a high likelihood of significant mechanical and electrical issues, primarily centered around its…
Best Model Years
For the FC generation, later S5 models (1989-1991) generally benefited from minor reliability improvements, but all rotary RX-7s require meticulous care. A well-documented, lower-mileage example from any year is preferable.
Years to Avoid
Avoid any model year with vague or no service history, evidence of consistent neglect, or a known 'hot start' issue without a professional compression test.
Biggest Strengths
- Robust chassis and suspension design
- Timeless and attractive styling
- Engaging driving dynamics
What Tends to Fail First on the 1987 Mazda RX-7
The systems that tend to fail first on the 1987 Mazda RX-7, 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.
Apex seals and coolant O-rings are primary wear items, leading to compression loss, misfires, hard starting (especially when warm), and eventual engine rebuilds. Carbon buildup from short trips exacerbates these issues.
The Hitachi HT18 turbocharger found on Turbo II models is prone to bearing wear and oil seal failure, leading to excessive smoke from the exhaust, reduced boost, and potential catastrophic turbo failure if neglected.
Brittle wiring, failing sensors (e.g., TPS, O2), sticky relays, and numerous aging vacuum lines developing leaks can cause erratic engine behavior, starting difficulties, idle issues, and non-functional accessories like pop-up headlights…
1987 Mazda RX-7 Mileage Danger Zones
The mileage windows when the 1987 Mazda RX-7 most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Early Warning Zone
At this mileage, an RX-7 should ideally be pristine. Any signs of neglect, poor starting, or excessive oil consumption are major red flags, indicating potential early engine wear or deferred maintenance.
Critical Inspection Zone
This mileage is a major crossroads for rotary engines. A compression test is absolutely vital here. If proper maintenance hasn't been meticulous, apex and coolant seals may be nearing their end.
Rebuild Horizon
Most well-maintained rotary engines will be approaching or needing a rebuild around this mileage. Expect significant wear across many components. Deferred maintenance will almost certainly result in catastrophic failure soon.
Enthusiast/Restoration Zone
At this mileage, an RX-7 has either been meticulously maintained and possibly rebuilt, or it's a project car. Do not expect reliable daily driving without significant investment and a comprehensive overhaul. Budget for engine, transmissi…
1987 Mazda RX-7 Ownership Cost Outlook
What it typically costs to keep the 1987 Mazda RX-7 on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.
Annual Maintenance
$800-1,500 (assuming no major failures)
Moderate Repairs
$1,000-3,000 annually (for aging components, turbo rebuilds, electrical fixes)
How Long Does the 1987 Mazda RX-7 Last?
For an RX-7, mileage is less of a concern than the engine's compression test results and the thoroughness of its maintenance history. A 100,000-mile engine with documented rebuilds and meticulous care can be a better buy than a 60,000-mile engine showing signs of neglect.
