Ford Focus Mk1 (C170)

Production Years: 1998 - 20042 Documented Faults

The Mk1 Ford Focus (C170) revolutionized the family hatchback market in 1998 with its striking 'New Edge' styling and the incredibly capable 'Control Blade' rear suspension. It is now widely regarded as a modern classic, offering handling precision that shamed much more expensive cars of its era. In the UK, it was the definitive family car, but survivors are now battling aggressive body rust and tired steering components, pushing them into the banger or enthusiast category. It perfectly suits DIY mechanics or driving enthusiasts looking for a cheap, iconic benchmark of 90s chassis engineering.
