Steve, welcome aboard. I am not a London Roadster owner so I will leave it to one of them to answer your car specific questions.
As a new owner, the very best advice I can give you is to go get a glass of water (or whatever) and settle down in front of your computer for a long session of reading past posts on this site. You will spend your time best by becoming very familiar and comfortable using the “search” function at the top of this page. You will find that it is hard to ask a question that has not already been asked and answered. (Please don’t think I am trying to discourage asking questions.)
Please post photos of your new ride and be as specific as you can when asking questions. You will get necessary responses, sometimes within minutes and sometimes (but more rare) within 24 hours.
