A bit off the subject , but in 1980 I attended the Country Gents event at Wigram.
Sybil Lupp was there in her V12 E Type and she proudly showed us the engine they had been modifying to give it a little more "performance".
The car was an unusual colour which she explained was the same as that of a favorite gown of hers, a sample of which she had sent to the factory for matching.
