- ✓Assume the car leaks unless proven otherwise. Water ingress is the Roadster's biggest enemy.
- ✓Check the SAM unit (behind the dash) and the ECU (on the airbox) for signs of water damage.
- ✓The soft top (canopy) can shrink over time; check that it seals properly at the side rails.
- ✓Listen for the turbo "whistle"; a loud siren noise indicates a failing turbo.
