Sorry to hear this. I agree it doesn't look good. I notice that everything is expensive, which means fewer buyers, which means it's harder to find feedback on the company. I bet if he "sells" that $1.4M Bentley, he will close up the shop and be gone for quite a while.

Beware: I paid almost $15K to Audio Zoom Zoom (Netherlands) for a Kondo Souga amplifier and all communication stopped completely as soon as the money was paid. Guy goes by the name Varchi.
