MPG should be, if all is in fine order, between 27 and 30.5 mpg. I averaged 28.5 mostly when not in stop and go traffic and mostly country road driving, constant speeds, and not aggressively or often.
If you buy a GTI, it's for a bit of fun. Corner to corner A/B roads are fun. If you drive those roads with economy in mind, a GTI is the wrong car.
35-40mpg is easy, but you might as well get a derv if you're concerned about that. Because a derv Golf will do everything a GTI will at 35-40mpg.
RCD510 DAB is an easy retrofit. And cheap - 150 quid or so. You might want to read into the battery drain issue on earlier mk5s. Do a search.
Id be happy to average 27-30MPG only reason i asked is because i have also been told its more 18-22MPG by friends.
My 250 Miles should cost me around £50 of premium fuel going by those MPG figures which i would be more than happy to pay, i currently put in £35 a week.
I did do a search and seen i could have battery drain issues but can be sorted. What about the DAB, i'm guessing i would have to sort the Arial out?
What should i look out for? I have heard about the rust and making sure the cam belt has been replaced, and the seats can tear a little.
My budget is around £6k would like to get a 2007-2008 model.
