To be fair the common rail versions don't rattle.Anyhoo horses for courses, never said you were a pusser btw ;-)
I too came from a VAG 140bhp diesel ......I do exactly the same journeys in my GTi and I see .... 10mpg drop
The fact that you are considering a GiT is that you will accept the additional costs. These, there will be but will also leave a smile on your face.Just go for it, you know you want to !
Diseasal is more expensive, it stinks and produces embarassing smoke clouds. Yes, you get more mpg than a GTI, so what. Diseasals should be be rated in ypg (yawns per gallon)
