The car is described as being in 'generally good, age-related condition' with some recent renovation work completed in 2018. While it has undergone some refurbishment, the description also mentions that the interior is 'almost entirely original' suggesting some wear consistent with its age. The gearbox has a known issue that requires attention. Therefore, a condition rating of 'Good' seems appropriate as it balances the positive aspects of the renovation with the car's age-related wear and the gearbox issue.
