- ✓Inspect the turbocharger on the 698cc engine for smoking or boost leaks; the engine requires meticulous servicing to survive past 70,000 miles.
- ✓Test the electric folding soft top or removable hardtop for smooth operation and tight seals.
- ✓Check the air conditioning pipes, which run the length of the car and frequently corrode and leak.
