Is that Gurston down in Broadchalke?
....It most certainly is Gurston Down
Not the greatest for spectating but a very good turn out of cars.
Here's another classic Jaguar at the same Gurston Down event:
^ Jaguar C-type.
I grew up with a friend whose family had a D-type and also a full race 3.8 saloon as well as other very fast cars - All road legal and before the feckin' 70 mph limit got introduced.
