For DD i would rather just buy the 1.8 version.

Slightly less mpg however much more performance for hills and daily driving.

Buying small capacity cars thinking you save money on fuel = fail as you have to rag them when you meet hills.

TBH i would spend 3k on a passat PD130 (like i did) as i hardly ever need to change out of gear. 130hp 225lb/ft, £300 remap sees 170hp 300lb/ft.
