All good points & valid! You can't tell one BMW from another & in a sideways point of view you help define my point. The Xfire looks like nothin' else! And, frankly, with its new 'grooved' hood the Sebring does kinda borrow the Xfire's looks.........kinda. The Mopar grills drive me crazy, though, especially on the Rams: if they get any bigger (& therefore more 'manly') you might just as well glue a Royce grill on them & be done with it!
As to the Benz's being created down the road, unless you would have pointed it out the average well-heeled buyer would never guess!
