And to add to that post I will even stick my neck out and say with the right conditions, no traffic and less fuel in the tank or stuff/crap in the boot, Im convinced I could get 40mpg. (might get pulled or a few strange looks) but Im sure its possible.
And probably a few choice words too - sommat like "WTF are you driving an R32 like a granny, give it to me, and I'll drive it like it was made for!"
If you also look at the amount of time it took me, it was only about 2-3mins over what it usually takes me. So all in all... not bad at all for a 3.2 
At the other end of the scale, look at the instantaneous fuel consuption when you hold the pedal to the metal - that will make you wince!

Said it before and I will say it again.... "cheaper to run than an ED30" you can quote me on that

Hmmmmmmm. If an R32 and an Ed30 are both driven in
identical manners, then I would still have to say that the Ed30 would still be more economical - not only on fuel, but also because the R32 is a higher insurance group, higher road tax, and costs more to service and maintain (Haldex oil and filter change, 6 spark plugs instead of 4, a more difficult timing belt with an extra idler roller, larger brake components [which will naturally cost more at the stealers

]).
