I don't think it started life as a factory prepped car. It probably was a regular E-type that was later modified and used for racing. Very little is still '63 vintage except the tub. I guess the rest of the story will be told Sat. afternoon. If it's $100K to $150K, it's a later build-up. If it's $500K+, then Sir Lyons oversaw the build.
Still VERY nice.
