Hi Matt,
I have been exporting cars here to Europe in about 20 years now, and have personally brought over a couple of Vipers for myself..a 97 GTS and 99 ACR.
There is a few things to do on your part, first getting the payment into your bankaccount before you ship it, do the local paperwork and get the car to the port. Wirepayment from his bank to yours is the most secure and fastest way of doing it, just make shure you give him your banks bankcode with your accountnumber..the routingnumber you don't have to worry about since we don't use them over here.
Be careful when you have the car delivered to the nearest port, if you do, since many cars do get some scrapes and small dents during shipping, make shure your truckingcompany has a solid reputation and a good insurance, and make shure you find a freightforwarder that know how to tie down a Viper in the container if you ship with container (talking from lots of bad experience), if you ship roll on roll off, make shure that there are no loose parts in the car since they will most likely never make it to destination (talking of experience).
Sign off all the original documents and send them in to your local DMW, and make up a SOLID bill of sale and buyers agreement before you ship the car, many overseas buyer want a low bill of sale amount, since we have very high salestax in most of Europe..in my case 25%, so this will have to be an agreement between you and the seller. The title has to follow the car, but I would send it to the freightforwarder with registrered mail so they have to sign for it..that way you are off the hook if something goes wrong or get lost.
I do have some international freightforwarders that I use myself if you need some asistance in that area.
I hope this helped you..if not please feel free to ask any questions.
Sincerely,
Kurt
