Shipping is not a real problem...lots of shippers out there.
Most important thing is to get someone to physically look at the car, photos always look better.
Payment is not an issue with PayPal or other types of payment. I have even paid with a cashier's check. If you go that route, you can inquire to other folks as to the character of the person. For a small group like the Puma folks, chances are most people know each other, or have references.
