This thread is pretty clean so far guys but please make sure it doesn't turn into an Autobarn Sledge-fest or will have to be closed.
For the record I quite like my local Autobarn, although smaller than the local Super-Cheap they have a much nicer layout and friendlier staff. They may not know everything, no one does - except mothers, but if you know what it is you are chasing it's no worries.
I've never had a problem with them.
