Condition 

6

The car has undergone significant modifications including a Rover V8 engine swap and a five-speed transmission. It has been refinished in black and has Minilite-style wheels. However, the description notes blemishes visible in the gallery, and the odometer reading is considered 'Not Actual Mileage' with a discrepancy. Additionally, it cannot pass California emissions, indicating potential mechanical or exhaust system issues that require attention. These factors suggest a 'Good' condition rating, requiring some reconditioning.
