I assumed longshaft was an error as it looks a shortshaft.

OK it had some kit but I'd far rather one 2yrs old for £1500 and find the kit myself. Last year when we were looking for ours new if I'd seen a 2014 used for £800 off the usual discounted new price I'd have been in Poole to buy in hours.
I thought that outfit would have had interest but one pain was that the guy wanted to keep it for another 4-6wks after you'd purchased. No way would I have bought under those conditions.
