I just got my MKX. I love it so far. It rides smooth, good power. Sometimes it surprises me with the acceleration. I traded in my Mountaineer and I don't feel I gave up any room or space. I'm getting a lot of looks on the street! The base model has everything you need. I sprung for the vista roof. If you want the nav system or the THX sound system about $5000 more.
I like the fact that all the controls for the audio and temperature are in the steering wheel.
