I've had the chance to drive both cars in the past........didn't see, hear, smell or feel any similarities at all to be honest........and the Five Hundred is so under powered with the 3L V6 it's not even funny (I won't even comment on the AWD model). Ford really dripped the ball by not bringing that model (as well as the Freestyle & Lincoln Zephyr......er sorry, the now MKZ) to market with their new 3.5L V6. :whistles:
