Vehicle Details

AI Listing Summary

This 1956 Bentley S1 has been converted to a drophead coupe style and features a maroon exterior with a beige interior. The car is powered by a 4.9-liter inline-six and a four-speed automatic transmission, with 2,400 miles shown on the odometer.
While cosmetically appealing, the air conditioning is non-functional and the underbody shows corrosion, indicating some reconditioning will be needed.

Condition 

6

The car has undergone a conversion from a four-door saloon to a drophead coupe style, which is a significant modification. While the interior and exterior present well with beige leather and maroon paint, the listing notes that the air conditioning does not work and there is noted corrosion on underbody components. These issues, along with the conversion itself, suggest it's in good, but not excellent, condition, requiring some reconditioning.
