Max:
I would not be comfortable in doing a long distance deal with a seller who has clearly demonstrated that he cannot be trusted.
If you are keen on getting a car from the South Florida area, I would drop an e-mail to Pedro of Pedro's Garage (
www.pedrosgarage.com) and arrange for him to look at any car that you are seriously thinking of buying. He is very knowledgeable, a Porsche nut, and completely trustworthy.
He does PPI's and the peace of mind it will bring you will more than pay for the price of his services.
Regards, Maurice.
