I like the Ford site better. The graphics on both sites are simple yet effective. Who doesn't love a picture of a classic automobile? The text on the Ferrari site is difficult to understand. You seem to be having some syntax problems but both sites load quickly and the colors are good. As your sites get mote content, they will be great for enthusiasts of both cars.
What i don't like is the deliberate google ads placement, there is no defined navigation because of this. Put me off http://ford-mercury.leelio.com/ instantly, sorry
your ad placement is nice on the ford site, it's a little tricky on the ferrari site. maybe you can add in some stats or youtube videos?
My first thought on both the sites was the huge amount fo text that i was faced with...maybe split up the cintent to make it look less imposing?
I kind of like the design. You should probably get a native English speaker to edit your writing, as some of those translations are a bit awkward.
