I had the complete opposite experience with South Yarra. I got the "ill ask my manager" line repeatedly even though my offer never changed. They even rang me the next day and asked if i had considered *their* offer. To that I replied it was you guys that were considering *my* offer!
The guy was like "ill go ask my manager and call you back in 5 minutes" I had to laugh!

That was a little while ago though. With all the fantastic reviews I hear about Burwin I think i'll head out there to buy my next VW.
