Just to update this, I'm rubbish at making decisions. 
Was quite interested in a 207 GT 1.6HDi 110 that's fairly local....but it's a year too old for the £30 tax so is £110 tax which is annoying, but not the end of the world. But the avg mpg figure is only 56mpg...how can that even be possible with newer tech, lower CC and a VNT turbo!?
306 HDi is 54mpg avg on the same database.
I have also found a 207 S (pov spec
) with a 1.6HDi 92 (not the older 90). This is £20 tax and an avg mpg figure of 67mpg!!
How can the same engine be so different? Of course I don't expect to get that MPG, but its useful to compare them. I'm struggling to find any info on the 92ps variant, and was wondering if anyone on here knows what makes it so much more efficient?
Also, are the figures done with extra load on the engine (AC on for example?) that might make the better specced one seem less efficient? Just cant get my head around how the same engine in the same car with just a different map (I assume) can vary so much.
