Not following instructions is not a reason to call red flags on Alaskan T/A. Barry is a great guy and specified in rudimentary instructions how he wanted payment.
I have bought from Barry and even been visited by him, he has done more for the hobby on a slow day than most have in a decade. He is a busy guy and is well known as being a guru.
I can agree with a busy guy and knowing quite a bit about cars. But when an issue comes up it needs to be dealt with. Mistakes are made by buyers and sellers. Be very careful when you put someone on a pedestal-they will fall off.
