There should be no discussion IMO. If you are going to take your car to any country, that is one of the best. Find the right dealership and they will pamper that car like no one can.

As to the autobahn, it has been many years since I lived there and quite a few since I last visited. You will enjoy, but like suggested, do be mindful of the parts that have limits. Also, if you see someone flashing their headlights at you while in the fast lane, MOVE.

Enjoy and keep us updated.
