Ford Fiesta Mk5 (BE91 facelift) Common Problems & Reliability
The UK-market Mk5 Fiesta is effectively a heavy facelift of the Mk4 BE91, bringing sharper 'New Edge' styling and a much tidier, more mature cabin. It remained positioned as a dynamic, affordable supermini, offering an excellent chassis that made it genuinely fun to drive on twisting B-roads. Because it is mechanically very similar to the Mk4, buyers should focus on rust, suspension wear, and minor electrical faults rather than expecting modern refinement. It is an ideal, ultra-budget purchase for young drivers or commuters who want a simple, engaging car with incredibly cheap replacement parts.
