Hello Jim,
define vicinity. Europe is small...
If you visit UK and you are a old car nut you have to visit the Goodwood revival meeting. In September it is a british car event with a Healey competition in netherland Zandvoort on the other side of the channel . Or Beaulieu autojumble in sept. Not near to London but amazing. I was in London last year with my 14 years old daughter, and we speak sometimes about our trip to camden lock town stabels market. A funny shopping trip very vintage and colourfull.
Also a must is the Portobello road market. Some dealers ar having expensive old Healey model cars ....for you
The crown juwels are also interesting. Use the tube, it is very fast to travel with the London people trough the city. But mind the gap...
If you have a week ticket for the tube from National Rail you can also travel with the double decker bus . Very funny to sit ubstairs on the front.
But back to your question. Travel at september and rent a car to drive to Goodwood. This was the best what I have seen of our hobby. Attention : You haveo to be weared time area authentic..
Bye Michel- who love London
