Condition 

4

The car has had a significant engine and transmission swap (V8 and automatic) which is a major modification from its original state. The description mentions a hole in the soft top, missing side curtains, missing paint on the door sills, and that the true mileage is unknown. While the V8 conversion and some mechanicals like the radiator and speedometer were serviced, these cosmetic and originality issues bring the condition down.
