Welcome to the forum Robert,
youll find the members on here are a friendly and helpful bunch :)
sorry to hear about your bad experience but it does sound to me they thought you were timewasters.
The prejudging of people in the motor trade is rife, I can say this as iv worked in it. The one thing i learnt is you can't judge a book by its cover which this sounds like what Audi have done for what ever reason.
What were the 2 Audis you wanted to test?
Cheers
steve
