The A3 had a nice ergonomic yoke, if you like that sort of thing, bristling with buttons including AP disconnect and electric trim, though myself I prefer to do it manually. Good Avionics stack, including [King I think?] IFR approaved GPS , AP with NAV/ALT/HDG/APR plus rate of decent and climb, dual NAV/COM, Dual VOR, comfy seats with head rests, EGT guage etc etc. No key needed, its all done be a bank of switches located above the windscreen. Nice aircraft to fly. As drauk mentioned they're 2000 models I think, so they have had about 3 years use. The 172s are just as nice, if you like a high wing. Makes me feel like I'm sitting in a gold fish bowl myself. I'll post a couple of pics here if I can find them. When are you going? I'm there in August.....
Cheers
