What to check on a 2009 Porsche 911 before buying
The three areas where failed first tests most often had a fault, 2023–2025.
- Lamps and electrics. Ask someone to watch while you work the brake lights, indicators, sidelights, dipped and main beam, and the number-plate lamps.
- Tyres. Worth checking the tread depth across the whole width of each tyre, and the sidewalls for cuts, cracks and bulges.
- Body and underside. Worth looking underneath with a torch at the sills, floor and mountings for corrosion, and at the rubber boots on the drive shafts for splits.
