All cars are expensive. VRT is cruel. The Focus is the best car in it's class - a fact acknowledged by virtually every commentator, but is not the most expensive.
Some models are very well equipped. All are well built safe and reliable.
I'm biased, since I benefit from the Ford Employees scheme and having owned 6 of them so far (I'm selling 2 btw) but there's nothing to beat them imho.
The TDCI is a great engine. 1.6 110bhp version is the best. Joint engine development with Peugeot.
