2002 · PorscheBoxster S
What the data shows
This Boxster S is a gem to drive, but the M96 engine needs a few big-ticket items verified. The IMS bearing is the top concern—if not upgraded, factor in a $3k repair. The asking price is a stretch relative to market, so use repair needs as leverage. A pre-purchase inspection by a Porsche specialist is highly reasonable before buying.

Reflects the open findings; items the owner handled are excluded.
Confirm these before you buy. If you or a mechanic can verify them, that clears the car instead of ruling it out.
IMS Bearing Failure Risk
The intermediate shaft (IMS) bearing in M96 engines is known to fail, often catastrophically, destroying the engine. On early cars like this 2002, it's a single-row sealed bearing prone to fatigue. At 76k miles, if still original, failure risk is moderate to high.
Costly repairs, but not urgent to verify before you buy. Price them out and use them to negotiate.
Rear Main Seal (RMS) Oil Leak
The RMS is a common leak point on the M96 engine, often showing as oil drips between the engine and transmission. It's not a safety risk but can get worse and lead to oil loss.
Coolant Pipe (Vent Pipe) Cracking
The plastic coolant vent pipes on the M96 engine become brittle over time and can crack, causing sudden coolant loss and overheating. Many owners replace them with aftermarket aluminum versions.
Minor wear typical for the car’s age. Not worth negotiating over, but good to track as an owner.
Air/Oil Separator (AOS) Failure
The AOS can clog or fail, leading to white smoke from the exhaust, rough idle, and increased oil consumption. It's a moderately common issue on M96 engines.
Ignition Coil Failure
Early M96 engines (2000-2004) are known for ignition coil failures, especially on cylinders bank 1. Symptoms include misfires, rough running, and check engine light.
Coolant Expansion Tank & Thermostat Service
The plastic coolant expansion tank can crack at the seams, and the thermostat is known to stick. Both are considered preventive maintenance items at 60-80k miles.
Brake Light Switch Recall (NHTSA 05V378000)
A recall for the brake light switch on 2002 Boxsters. The switch may fail, causing cruise control to disengage or brake lights to stay on. Should have been performed already by a dealer at no cost.
Verify: Cylinder Bore Scoring
Some M96 engines, including the 3.2L, have experienced cylinder bore scoring due to low oil levels, overheating, or debris. It's an uncommon but expensive issue.
What's working well
Manual Transmission — Robust Unit
The 6-speed manual is a solid gearbox with no major documented issues. At 76k miles, the clutch likely still has life if driven gently. Shifts should feel direct and smooth.
A healthy manual transmission means lower maintenance costs and better reliability compared to automatic options.
Every finding still open carries a question worth asking. Copy them as one message, already ordered by severity. Anything you have marked above drops off on its own.

Caution items with repair-cost context.
Each range is what that one item costs if it turns out to be present. Not every item will apply to this car, so they do not add up to a bill. Verify with a mechanic.
Asking is $13,500 against a typical $10,000 for this car and mileage. The work is the difference, not the sticker.
Negotiate your offer
At asking, this is about 35% above the market estimate (about $3,500). The documented repairs below are the kind of evidence buyers cite to start lower.
- Documented critical/major repairs of $4,500–$7,000 you can point to.
- Strongest items to raise first: IMS Bearing Failure Risk, Rear Main Seal (RMS) Oil Leak.
Pricing is in beta. The market estimate comes from research models and can be off by thousands on the same car, so check recent local listings before you rely on it. This is information to help you research, not a professional inspection, an appraisal, or financial advice.

8 things to check before you buy
2 major and 5 caution findings, turned into a walkthrough for the driveway. Answers save as you go.
Before you leave: Ask the seller not to start or move the car before you arrive. A sales-ready car has usually been warmed up, and a warm engine hides the startup smoke, rattles and rough idle that the first section is built around.
Everything on this list is what you can see standing next to the car. A shop on a lift sees the rest, and a written pre-purchase inspection listing parts and labor is what a seller has to answer to. Budget roughly $100 to $150 at an ASE-certified shop.
