Your friends shop is just too cool! Yours is nice too. I'd give my left ... for a shop like that & the contents. In the article that you provided the link for when he said he hardly paid attention to the house when he saw the shop while house shopping I know exactly what he means. When you spend most of your time there anyway, why not.
If you or your friend are not familiar with advrider.com I know everyone there would get a big kick out of some photos of his shop & bikes on the garage forum etc. If he's already posted there let me know in case I missed it. Thanks for shareing.
