The fifth-generation Ford Fiesta (often called Mk5 or Mk6 depending on the market) marked a real break from its predecessors. Launched in 2002, it abandoned rounded lines for a more cubic (New Edge) design, greatly improving interior space. Based on an excellent platform, it established itself as one of the most dynamic and pleasant-to-drive city cars in its category. While Phase 1 (2002-2005) suffered from a very plastic and austere interior finish, the late 2005 facelift (Phase 2) corrected this with a soft-touch dashboard and better sound insulation. In terms of reliability, it presents a very mixed record: the gasoline engines (partially developed with Yamaha) are exemplarily robust, while the diesels (from PSA Peugeot-Citroën) account for the majority of costly breakdowns.
The 2002-2008 Ford Fiesta is an excellent used city car, provided you choose the right engine. The gasoline versions (particularly the 1.25 and 1.4 16v) are models of robustness and offer a driving experience superior to the average for the time, thanks to a very successful chassis. In contrast, the diesel versions (TDCi), although economical, should be avoided or purchased with extreme caution due to potentially higher repair costs than the vehicle's value (especially the 1.6 TDCi). It is imperative to prioritize a Phase 2 model (after 2005) with a gasoline engine for a worry-free purchase.
