Yeah I had a 182 for three and a half years prior to the 200. The 200 is a massive improvement over the 182 in lots of ways. More refined, more solid, much more of a car and less of a toy, as I felt the 182 was.
RUK have taken the 197 (which is/was a brilliant car in it's own right) and improved on it in the 200.
MPG wise it's worse, worse than the 197 much the same as the 197 was worse than the 182 (and so on).
Low thirties is 'achieveable' if driven carefully but at present I seem to be sitting between 20 and 25 MPG.
£120 of fuel got me approx 500 miles.
