I don't understand all the hate on this forum! So what if he has a hobby that is basically a form of OCD? He's happy, he's not doing any harm to anyone and I imagine he's over the moon with his car, knowing that it's completely individual and exactly how he wants it.
It's a bit unfair to make comments on his personality or about his social life and wether or not he has a family. For all you know he's married with kids and is a really nice guy!
I'm guessing you all saw the Dyson that he did too?
EDIT: I know this topic is a bit old but I got to this link via another topic on the same subject recently.
