Bought my 166 for about £800 . Bit of an impulse buy as fancied summit different (and love Alfas)
Nicley made.. comfortable .. great noise . I had the steptronic and the box is not known for giving issues .
Lots of toys and i loved the car !
Common issues are cam belts snapping and taking 24v out (happened on mine with a 3.5k bill to the previous owner) and fast wear rear suspension components which give very interesting handling traits .
You can throw it about but its a big car .
Biggest issue was fuel . I only use the car for work and back (8 miles each way) and i was putting over £200 a month in it compared to my mondeo which does it for £70 . Best i ever seen was 31mpg at 65 on cruise on a1 at 2am . mostly it was low teens .
If you can keep it in fuel go for it . Only issue i had was a split hose near the expansion bottle.. Nothing else failed or fell off in a year of ownership
