Guitar shop owner, possibly nuts?

There's a guitar sitting in the shop that I really want to buy. It's a gibson Cloud 9, and there's 2 in the shop. it's 8,750$ and the owner of the shop plays both of them. I had the money and had finished buying and refurbishing 3 guitars used from a bad home. As I was making the purchase he asked how many guitars I owned and I told him I couldn't quite count. He told me he wouldn't sell it to me on the grounds that it would not be going to a good home and he liked it too much. Is this illegal or just very stupid?
