Thanks for all your replies.
Yeah it definitely burns. I've never had an issue with a seller or buyer in my 35+ car sale/purchases. I've handed this off to my lawyers but as always, it pretty cost prohibitive. The seller just needs to do the right thing but it looks more like he's trying to ignore the situation altogether and steal peoples money.
On the bright side, I ended up getting a Caterham instead since I was so annoyed with this whole deal. I'll try again with an Alfa in a year or two. The community seems to be very strong and encouraging and that's half the fun!
