the good bits...
they are cheap compared to manuals,
they have a proper torque convertor automatic, not a dopey cvt like the current wrx,
it has nice big paddles, fixed to the steering column,
yes, it does blip the throttle on downshift but ...
the bad bits...
it's redundant as the downshifts are so slow,
the manual shift is backwards, i.e. push lever forward to shift up, pull back to go down a gear,
the car has less torque than a manual and feels laggier.
sounds crappier too,
finally, ones i've seen also miss out on the big brakes.
