Well all I can say is Land Rover really can build cars that work :) 2300 miles, no dramas, no problems - and an average of 18.9mpg which is not bad when you consider how much autobahn/de-restricted roads there were and we were tootling on the limiter (135mph).
Got a *lot* of odd looks tho, and did not see a single Range Rover on the journey from France through Belgium, The Netherlands, Germany and Poland, or on the way back! Saw a few Brit ones at the tunnel terminal tho. I got pulled out on a few times - the end result being the other drivers pulling back across because that 3 ton tank really was going that fast :)
Fuel costs were fairly random ... 1.4 euros in Germany per litre, yet under a quid in Poland just over the border! Warsaw was different - not as I had imagined, but it was grey hehe.
