Never seen a single harsh word uttered in the general vicinity of the F50, but it seems not to be too popular around here.
I used to like the F40 better than it, but in time I grew to like the F50 better. I am a big fan of the F50. But, neither of these cars is high on my list of Ferraris that I would get. Believe it or not, top dog for me would be the good old F355. Why you ask? To me, the differences in performance capabilities of contemporary Ferraris are so slight, that it is all about the appearance. And I think no car captures the Ferrari look as well as the 355.

It has a little more compact look, like a street car, unlike the F40 and F50, which look more like track cars. Call me old-fashioned, but I like a street car that sticks to its street car looks.
I do like this rear view of the F50 very much.
