My British Leyland Jaguar XJS wasn’t built in Leyland either. Just to confuse you even more Bristol siddeley railway diesel engines were built in a suburb of Bristol called Coventry
Interesting place. I see you have prevented me asking where it is by providing a google maps link... If you go near Ipswich there is a museum of public transport, can't remember the name but not only can you walk around the exhibits you can sit in them. I would recommend it.
