My partner says that is absolutely right. When the V-12 first came out, he had a friend who was a marketing exec for BL, and he had a V-12 company car (!). That is exactly how things work, L, of course, being Low gear hold.
What a beautiful looking E, and a great colour.
On the subject of parts, SNG Barrett are excellent, as are BritParts, and there is also a smaller outfit called Growler Parts (on-line) who, although not having such a large range of bits, does charge very reasonable prices for genuine Jaguar parts.
Good luck with the E - extremely happy growling!
