Ive had two 182s and two 197s, prefer the 197 although I would say after a short time in a 197 you might find it dull, its only when you start to drive it very hard you appreciate just how good it is. 197 is a lot nicer to live with day to day.
182 is definitely better in terms of economy though, 197 would average high 26's for me whereas 182 would easily do 32/33.
