Buyer’s notes
About the Porsche 911 GT3 (997)
The 997 GT3 took the racing-derived Mezger flat-six to 3.6 litres and 415 PS in the narrow body, with an 8,400 rpm red line and a six-speed manual gearbox in every car. Developed by Porsche’s GT department, it refined the formula of the 996 GT3 into the definitive driver’s 911 of its era.
What moves the price
- Version: the RS cars sit above the standard GT3, and the 3.8-litre Gen 2 cars from 2009 refined the formula further.
- The Mezger engine and the manual-only gearbox are what the market pays for.
- Originality and use: unmodified, well-documented cars with little circuit time are worth most.
Before you buy, check
- Engine over-rev records, which a Porsche specialist can read from the engine management system.
- The engine’s coolant pipes: the original bonded pipes can come apart, and pinned or replaced pipes are a plus.
- Evidence of track use, and the condition of the clutch and brakes that goes with it.
