Congratulations on your marriage Benjy, Bath is a lovely city, glad you both enjoyed your stay
I cant believe you have seen so many zeds! I live in Bath and have only seen around four in the space of six months and most of the time people refuse to wave back at me . I own the second one, have just treated it to a clean, shame it was filthy when you saw it, and my friend owns the Black Edition 370 that you probably saw (very nice!). He isn't actually a member on the forum, I am trying to persuade him to join.
I am not sure about number one and four, but have recently discovered that the lovely number three belongs Bockaaarck. I have also seen quite a few s14's recently, the odd skyline and I know a few Zealou5 Jap cars that are based within the Bath area - all getting ready for Japfest
