As far as bad ones go, Bradford Audi on various occasions were pretty terrible, when I was looking to pick up an S3 last year, went had a browse, showed interest in a couple of cars, entered showroom hung around got a few looks from various staff, no one approached, left it at that.
Mate on another occasion looking to put an order in for the new S3, arranged a week prior to test drive one at Bradford, rang mid week confirmed with someone time he was arriving, all was good they confirmed, turned up on the saturday for the test drive to be told the person he had spoken too was on annual leave that day and there was no S3 on site at all despite what had been confirmed on the phone, obviously pretty annoyed by the situation as he had driven there with the intent on possibly placing an order for a 35K car, salesman gave a half ***** "sorry about that" and that was it, As I'm only early 20's as is my mate cant help but feel they took that into account which is a terrible thing to do if that's the case.
In comparison rang Leeds Audi directly from leaving Bradford this was around 4pm on a saturday afternoon spoke to a gent there and within half an hour it was all arranged drove over spent a fair amount of time test driving and just the general level of service given was miles above, for anyone considering Bradford from my experience even if its closer I'd take the extra drive time to go to a far and above better branch.
