UPDATE:
I drove an MKX today, it drove nicely and the interior was nice as well. I think Lincoln did a good job w/ the vehicle. I drove a Dark Ink Blue model w/ the tan interior. It looked nice, but the blue looks almost black, even in direct sunlight. I'm not used to driving a FWD car, it was awkward feeling the torque steer while pulling out of the dealer. We'd get AWD if we got either an MKX or Edge, so that wouldn't be as much of a problem, though.
There was also an Edge in the new Light Ice Blue color, that's nice as well. I didn't drive one of these today.
One other note, I think it's funny how little salespeople actually know about the cars they sell. The salesperson I drove w/ just moved from a Ford only dealer to Ford-Lincoln-Mercury, so I'll cut him a little slack. For example, he didn't know the MKX had available heated rear seats. Also, doesn't the MKX have more sound insulation than the Edge? He said it doesn't but I think it does, am I right? He was a really nice guy though.
My mom and I also drove a Taurus X as well. It drove nicely also. It was an Eddie Bauer model, white w/ tan interior and the 18"s.
All I can say is I'm waiting for the Flex to come out. The salesperson I was with today says he's going to buy one when they come out.
