I can never figure out how to reply to these posts... So hopefully you see this reply re the MKX....
I have a 2007 MKX AWD. Two years later I am as satisfied now as when I bought it... That is, Extremely satisfied... Regarding mileage, not good in the city... On the highway with cruise control on and mostly using +/- to increase/decrease speed, the best I've done at 70/75 mph is 23.5 mpg per the guage... I will say, I swithched over to the MKX after many years of having Mercury Grand Marquis'.. The ride is very good especially around turns, not much lean. Takes bumps well.. It has a vey clean and uncluttered look outside and inside. Switches are easy to use. (I don't have the nav or the sunroof). Do have THX which is incredible.. You may think (at least in my 2007) that the seats might be a little firm... However, when you've driven for 2/3 hours consecutive you begin to realize how friendly these seats are to your back... Just be careful if they are still selling the light dashboard. The glare is terrible on the light dashboard.. Mine is darker gray. And that's fine.. Yes, it does seem like it's whining when you hit the gas hard... But during two years I've had no problems. And passing at higher speeds is not a problem... Hope this helps... Good luck with your ultimate choice....
