■ Rust is a real problem for the Mk1 Focus, and the RS’s unique panels make restoration costs impressively pricey.

■ No longer cheap (or even affordable), this driver’s car is increasingly being tucked away in collections instead of being thrashed.

■ Too modern and shouty to be considered a classic, yet for many buyers too precious to be an everyday driver – despite great practicality.
