Aloha !

A Lexus is just an expensive Toyota, which it really shows on the inside and outside, no matter how much wood and leather they'll put into the dashboard and seats. It never really achieves the "wow" feeling you get when you enter a Mercedes, BMW or even a Jaguar nowadays. The Lexus isn't so pretty either, with it's cheap looking rear and dated designs.

I'd go for the Mondeo. It's not the best car of the three (obviously the Mercedes is) but the Mercedes is just ugly from some sides and looks like it's nose is too big. It looks, well, very heavy and in fact it is too. I don't really understand where BMW and Mercedes are going to with their designs anyway, most of their recent cars all look shit while brands like Ford and Opel are looking better and better.
