To avoid confusion with the model mentioned designations above:
1. Piper PA28-236 Dakota - later tapered wing, 235hp Lycoming O-540
2. Piper PA28-235 Pathfinder - Hershey bar wing, 235hp Lyoming O-540
3. Piper PA28-201T Turbo Dakota is basically a fixed gear Arrow III.
[Model numbers add a '1'to denote tapered wings 161/236/201 etc]
Piper had problems supplying parts earlier in 2014 (after computer glitches at the factory apparently) but not a real problem for PA28s in my experience.
Dakota is superb load hauler at a genuine 135 KIAS. There are many more C182s to choose from though.
Dakotas haven't been made since the early 80s.
