Have heard a lot of bad things about that dealership. Have visited it a couple of times, but I always got the 'Can you afford it sir' type of service, hence they lost out on 2 x S3's.
I use Audi Ridgeway up in Newbury, cracking bunch of lads in both service and sales. If you head up there, speak to Matt in servicing or Brian in Sales and say Bart recommended them to you. They'll look after you not saying they won't but my company has a very good relationship with them.
What car you looking at anyway?
