Hmmmm.... okay, I just read the Edmunds review. Maybe I should probably get over my 1990-era prejudice against Taurii!
Quite possibly if I'd had the car longer I would have been more impressed (e.g., if I'd had luggage, or managed to figure out how to use the electronics). I'll give it a fair shot next time. But I admit I'm still struggling to imagine choosing it over a 3-series (unless I had a bunch of luggage and/or passengers).
I know the 3-series will out-handle the Taurus in extreme situations but I don't usually push rentals that hard (usually... anymore

), but why I'd pick the Taurus:
-Heated/Cooled seats
-Sirius
-SYNC
-Size
-Seat comfort
-Touch screen display
-Trunk size
-Looks
We're all different and have different needs/preferences but that's my 2 cents.
