about 28mpg !!!
If you're paying £20 now on a 1.1 expect to pay about twice as much for a 2.8 Vr6 lump !
Realisticly, if insurance is not a problem repairs are about the same what ever VW you get.
Fuel costs are what can hit the pocket Bigtime!
Your 1.1 will do about 50mpg. So will my 1.9 TDI. GTI's about 35ish. As i'm sure will will have found out, I'd rather get 50mpg and pay enough now than a ridiculus 28mpg with the cost of fuel now !
