well, I don't see myself getting in on this group buy due to other things I am working on with the car but here is my $.02....
if I were in on this group buy, it would be a deal breaker if you went with this guy. I agree things come up and he "supposedly" had someone helping him, but does anyone know this guy personally? Is he local? If not, you cant trust what he is saying. Maybe he is genuine or maybe he's shady, no one really know so it's not a risk I'd take. Maybe I'm a bit jaded because of being burned before by people on other forums but those were lessons learned.
Now maybe one order is one thing, but an order of 10+ would be a sizable amount and I wouldn't want to be the one feeling guilty for choosing someone who ripped everyone off.
Again, this is just my $.02
