Talk to Hillcrest, but also try here:
Derek Lugar at Vantage VW ( I have taken the race school with him, and dealt with him quite a bit when I built my race car)
Craig Burns at Parsons VW in Middleton (he is the parts guy but can tell you the low-down on any car)he'll refer you to a sales guy after giving you the scoop.
Bob Coleman in (Colemans Autohaus) in Bridgewater is good to deal with too.
Other then that, canadatrader is your best bet, or go to Montreal or Toronto
