Welcome - and thanks for the nice S4/video link

. And no need to apologise, at all
I believe Sarg (on here...) might be considering selling his - with apologies to him if that's now not correct

..
There may be others, including (possibly...) me at some point in the future, but not right now. IMO you'd be better finding someone on here, as they tend to be better looked after, generally, and you can do a fair bit of research on what's been done on those cars by searching the following:
(1) the posting history of the car's owner and
(2) in some cases, reading the WITW ("What's In The Workshop") thread, if the car's been through Michaela's hands in the past
There are a few other good cars out there in the market, but they're hard to find, and it can be a bit of a lottery really - ask Marty, who recently bought his elsewhere...
