Thanks, and here goes nothing.
Thanks for all your advice folks - really appreciated.
I spoke again to the 'dealer' who said that because he was just a wholesaler (?) and not a dealer (difference being, I don't know!) I can get a RWC myself within 6 weeks and keep the rego. If the darn thing wasn't going for peanuts I'd run a mile. That, and the fact I've already paid a deposit. Anyway, pick it up tomorrow so we'll see what happens then. Fingers crossed...
Thanks again, really nice to get so much genuine interest and response. I like it here :D
