It's not on the AROC GT Register, so probably not an AROC member. Doesn't mean it's not been looked after, mind you. Those wheels don't do it for me, and look to be aftermarket, like the Q2. Have a good look at the paperwork if it's there to see what else has been upgraded. You could be on to a winner if a lot of little things have been done.
I'm thinking about changing my JTD to a V6, now that my mileage has gone right down. There's not a lot to choose from right now. Not that there ever were - only 400 or so ever sold in the UK. Go for it.
