just got back from a 1500mile round trip to see the mrs parents in germany, drove it cos i wanted to pick some stuff up and test the car on the autobahns, soo much roadworks throughout germany at the moment though slowed us right up, alot of the time struggled to do more than 70mph, but when i had chance to open it up i did, its a 3.0 cdti auto thats been chipped, its ex police so the speedo is calibrated, and i also confirmed it with teh sat nav, manufacture says 140mph, i was doing 145 at 3.5k revs quite happy with that but 140mph is only 26mpg were as 90 is 44mpg it certainly upset a few of the big luxury car drivers when they have to move over to let a vectra through
