Shame you are having to sell, suprised by your girlfriend, my wife asks to put the top down (no, the cars top) sooner than I would.
A couple of things with the ad
1) I wouldn't associate the work with the MOT, sounds like it only just scrapped through, I would list the work and then at the bottom just state "MOT until xx/x/2016"
2) Since October tax doesn't transfer with the vehicle, any outstanding is refunded to the seller when DVLA get the MOT.
3) A lot of people wont understand what you mean when you talk of the "lads" at Swansea, DVLA would be better.
4) The line about the Puma reads as if you are hinting that you might swap for a Puma, I would reword it.
Finally don't post the ad until you can include pictures, I have the ebay app on my windows phone so can take phone photos as I am creating the ad.
