In the end that's what did it for me with my 220. Although my economy figures aren't as bad as yours Harv, I did feel as though I was being robbed with every mile driven. I've swapped the 220 for a 250 and I'm delighted at the economy of the 2.5 V6 engine. I averaged 40.7 on the journey from Kent to the Midlands yesterday - absolutely fantastic, in my opinion, for a car with less than 1500 miles on the clock, and much the same as I eventually got out of the 220 (with 24,000 on the clock).
