Nope, I had seen the Grand C-Max; it looks much smaller than the Rondo. Not as long, and certainly not as tall. And as a tall guy, I certainly notice it when a car's roof is too low to my liking.
With that said, the C-Max looks great, and I'll certainly go take a look at it in person to see if my initial reaction to its pictures are founded are not. But it looks small to me.
I looked up the numbers and the Grand C-Max is about 4" shorter than the Rondo, and 2.5" lower than the Rondo. It is interesting that according to the specs I'm reading, the Grand C-Max is about 7" wider than a Rondo. That looks like a huge difference so it might just be a typo. In any case, I'm sure the Grand C-Max will drive much better than the Rondo considering it's a tad smaller and will be about 500 pounds lighter than the Rondo, which really is one of the biggest problems of the Rondo.
Regardless of its smaller size, it's another great entry for our market, and probably one of the first Fords in a VERY long time to peak my interest.
