thanks all, sounds like i really need to get that test drive sorted! has anyone else got experience in getting extended test drives? is this a VW thing? BMW and Porsche i've bought from before have both been more that willing to let you have a car all day or indeed overnight.
if i'm getting 35+ on my commute that would work mentally, i'm not fussed about it dropping on a hoon, i just don't want to spend all my regular driving concerned about MPG. really don't want to have another diesel if i can help it!
interesting about the comments on the improvements over time, my wife tiguan has improved massively over the years, its now on 22K and easily gets into the hugh 30's low 40s when driven normaly - its the 180 4 motion TDI, when we first got it i was abit worried as it was much more high 20's to low 30s in the same conditions
