Overview

The 1987 Pontiac Trans Am is a sporty two-door hatchback coupe from the third-generation (1982–1992) F-body lineup, positioned as Pontiac’s performance-focused alternative to the Camaro. It’s ideal for drivers who want classic American V8 character, sharp 1980s styling, and a car that still feels light and direct compared to many modern muscle cars. For 1987, the Trans Am continued to refine the formula with strong V8 options, available performance handling packages, and a driver-centric cockpit. Today it sits in the affordable classic-performance market, appealing to weekend cruisers, collectors, and DIY-friendly enthusiasts.

Key Features

1) Third-generation F-body platform with a low hood line, long hatch area, and a relatively light curb weight for the era, which helps performance and handling feel lively. 2) Engine choices that typically included V8 power, most notably the 5.0L (305) V8 in various tunes and the desirable 5.7L (350) V8 on certain Trans Am/Formula configurations depending on equipment and availability, with power delivered through manual or automatic transmissions. 3) Optional performance handling equipment on many Trans Ams, commonly including stiffer suspension tuning, performance shocks/struts, larger sway bars, and rear disc brakes on many models, helping the car feel more planted than standard trims. 4) Iconic Trans Am styling cues such as the aero front fascia, ground effects, rear spoiler, and available T-top roof panels that deliver the classic open-air experience. 5) Driver-focused interior with sport seats, a low seating position, and an available upgraded audio system for the time, making it a comfortable grand-touring cruiser when properly maintained.

Common Issues & Reliability

Shoppers searching “1987 Pontiac Trans Am reliability” should expect a classic car experience: strong fundamentals, but age-related wear and a few repeat trouble spots. Here are common “1987 Pontiac Trans Am problems” owners report: 1) Cooling system and overheating concerns: Radiators can clog internally, fan clutches weaken, and old hoses/thermostats fail—often showing up after long storage or in hot weather. Many owners see temp creep and coolant loss around 80,000–120,000 miles if the system hasn’t been refreshed. 2) T-top and hatch leaks: Weatherstrips shrink and harden with age, leading to water intrusion, wind noise, and musty carpets. Even well-kept cars may drip in heavy rain, and neglected leaks can cause floor pan rust and electrical gremlins. 3) Aging fuel/ignition drivability issues: Hesitation, hard starts, and rough idle are frequently traced to vacuum leaks, tired sensors, old injectors/carb components (depending on the setup), and weak ignition parts. Problems often appear gradually around 70,000–130,000 miles, especially if maintenance was inconsistent. 4) Electrical and interior electronics faults: Power window motors slow down, headlight motors/switches can act up, and dash/interior electronics may suffer from old grounds and brittle connectors. These are usually fixable, but they’re among the most common “1987 Pontiac Trans Am common issues” discussed by owners.
