Congrats and welcome to F club, now an official F-er 😉
Have a good nose about, ask all the burning questions as we're a laidback lot 😛
I bought my GS F from Hedge End funnily enough, if it is the same group from a few years back then they were a nice bunch.
What a lovely treat post-service, recommendation numero uno - get an exhaust!!!
Hampshire seems to have a lovely collection of F car owners these days so maybe you'll see some about and I am fairly sure there are atleast 2 (I know of) in the Southampton area.
I commented on your Simply Japanese thread, but the F forum is where you'll likely find meet up details etc, there is a thread going at the moment for late this year if you fancied it, I am trying my best to attend as many events as possible this year starting with FoS!
