Haynes Motor Museum, UK
As I was driving back to London and was in the proximity of Stonehenge, I saw a sign that said “Haynes Motor Museum”. Intrigued, I stopped on by. It turned out this was a museum of the namesake of all of my workshop manuals, and had an entire room of British Sports Cars! This was definitely one of the best museums I have ever been to and emphatically recommend it to any British sports car lover.
