2.2 - avoid, gutless laggy and rough as feck!
3.0 - smooth, not desperately quick but fairly economical
3.0S - rapid, a £200 remap or tuning box gives you around 320bhp and over 500lbs/ft ( I average about 30mpg on trips that I used to get 22/23 in the Zed)
Luxury - poverty spec
Premium Luxury - decent leather, better audio etc
Portfolio - best leather everywhere, 550w Bang & Olufsen 16 speaker stereo, DAB, heated/cooled seats, dual xenon cornering headlights etc etc etc
An S Portfolio is what I have but a very early one, I could have had a newer car but with less 'toys' but opted for an older one fully kitted out
