it depends on options.
Base spec with 17in wheels non msport was beaten by Ford Mondeo in last CAR magazine issue... they said it feels already a bit old. And it should after 5 years I guess! still the benchmark though, but unless well equipped it is not as good. In US this isn't an issue, hence it's winning tests, as your base model is quite advanced in Europe spec wise.
