VERY old TV ad

[whatnot1]

Saw this on one of those ad compilation shows a couple of years back. However the ad must date back to the 60s due to its non-pc nature.
The product was either the car or it's petrol (I think). The story-line was a young girl driving a sports car with young male in the passenger seat. She had changed down a gear to round a traffic island at speed when the passenger remarked "not bad driving....for a woman".
Would be grateful if anybody can remember the product. Thanks in anticipation.
