Russ, I do mainly into town drives 7 miles or so from the outskirts of Glasgow to the city centre and back, mpg on my 05 (55) gti is challenging, I get anywhere from 270 to 352 miles to 55 litre tank, you do the math. On continuous long motorway sppeds with cruise I have achieved circa 43mpg, however no car I have owned before can do the dull stuff and let me blow the cobwebs away like this car.
Cost wise, it's depressingly a good price this time last year for the same car with 20k I would have been willing to pay 14k. I want to cry..... LOL nah still had great fun, regardless :-)
