My old (independently owned) BMW dealer had a café and a lot of people used to drop in for a bacon butty and a brew. People would get to browse new stock and they had a sale rail of clothing next to it from which I bought loads of stuff.
They organised ride-outs and trips to the annual BMW bash in Germany + evening talks on stuff ranging from 'how to use the puncture repair kit' (and have a go at it) to 'an evening with Charlie Boorman'. Got to know a few people and some of us did France trips.
Pretty sure it all built dealer loyalty and helped shift a lot of bikes too.
Got taken over by a corporate BMW chain (same bunch as Guildford and Park Lane iirc). Closed the café, stopped all the social stuff....business dropped...shut down...became a s/h car dealership.
