Final Q I promise..

I'm guessing the MPG on the TDCI is better, more modern engine and management etc but is there a huge difference of just a few MPG...

do you know what I could expect from the TDDI on a mixed cycle, urban and main roads..

My wifes car is only doing around 35 to the gallon so looking for a big improvement over that. I think I will still be better off even if Diesel is a few more pence per litre..

cheers all, appreciate it.
