Update for those that may be interested.
Unfortunately I didn’t get to Somerset quick enough to prevent some other lucky person buying the 460 Paul advertised here and elsewhere. 100% my fault for not acting swiftly enough - procrastination🙄. Congratulations to Paul for the swift sale of what definitely looked like a very fine example of a 460.
Meantime, I’ve researched both the Norwich and Essex examples, which remain for sale, but have different issues that cause (picky) me some concern/reason for caution. Therefore, I am (for now at least) pausing on those two specific cars. Nevertheless, my search continues and if a member happens upon any information about a spectacular example of a UK LS 460 (<50k miles ideally) with FLSH coming to open market then I’d be extremely interested to hear about it.
Thanks again to all of you who responded to my original post and for your thoughts and wise words of advice all of which have been duly noted.
