Cheers mark, yeah I had the itch for one for a while now, after owning two 182's and a r26 I needed to try an 197 to complete the set!
So far I'm really enjoying it, fuel consumption doesn't seem as bad as I thought it would be, last £20 got me 100ish miles which is the same as what I got out of the 182's and meg. The interior is a much nicer place to be in, the seats are comfortable and give a great driving position. I love the way it drives as well, very slick and smooth gear change and the exhaust gives a nice subtle but addictive note.
Cons I would say are, it doesn't have that raw factor like the 182, feels very heavy and theirs very little feel through the wheel.
Also can be a bit 'flat' at times, but just like the 182's get it down a b-road, 3rd gear above 5k and it puts a smile on your face
