Condition 

7

The car has been refreshed cosmetically with a full repaint and wheel refurbishment, supported by photographic documentation. It also has some mechanical work done recently. However, the description also mentions that the car is showing just over 72,000 miles and has some wear visible in paint, interior, or wheels, so it is not in perfect condition.
