Jensen
P66 (1965 prototype)

Why it matters

The P66 is one of two prototypes built, and the only survivor according to its owner's site. It was the last car built while the Jensen brothers still controlled the company, which gives it a place in the firm's history.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

After considerable work between 2013 and 2015, the car was finally returned to the road in March 2015. It was shown at local events that summer and won Car of Show at the Lancaster Classic Car Show at the Birmingham NEC in November 2015.

In June 2016 it was displayed on the lawns of Goodwood House at the Festival of Speed.
