Condition 

7

The car is described as having a sound body, sills, and floors, with paintwork that presents well but is not concours. It has undergone significant recent mechanical work including cylinder head reconditioning, replacement of radiator, water pump, hoses, batteries, brake components, and carb float bowls. While mechanically sound with recent servicing, the paintwork not being concours and the presence of Rostyle wheels suggest it falls into the 'Very Good' category, requiring minor reconditioning for a higher finish.
