Hmm, the enthusiasm for the tea-making facilities is rather British.
But on a slightly more serious note, what would people expect to see or benefit from in a dealer visit?
For those buying new in the near future (or modding older vehicles) finding out all the goodies on the new cars is a plus.
For those on a more realistic budget, a good collection of pre-loved vehicles can be great.
For those who live locally, establishing strong(er) bonds with the staff is a plus.
For me, coming from three dealers away, I'm there for the drive, the ASN cameraderie, and (of course) the tea. Good to get some names to faces, on neutral ground, even if I will take some flack for my unwashed car.
