The Volkswagen Polo IV (type 9N for phase 1 from 2001 to 2005, and 9N3 for the facelift from 2005 to 2009) marks a major turning point for the Wolfsburg city car. Based on the PQ24 platform (shared with the Seat Ibiza 6L and Skoda Fabia Mk1), it made a spectacular leap forward in terms of interior finish, spaciousness, and comfort, approaching Golf standards. Phase 1 is distinguished by its double round headlights (Lupo style), while phase 2 (9N3) adopts a more aggressive 'V' front end. Although very well built, this generation suffered from early issues, particularly with its entry-level petrol engines (the famous 1.2 3-cylinders) and its running gear. The overall rating reflects an aging but robust car if the right engine is chosen.
The Volkswagen Polo IV is a city car that ages very well aesthetically, and its interior remarkably resists the wear and tear of time. However, its reliability record is very mixed. If you are looking for a petrol engine, absolutely avoid the 1.2 (3-cylinder) engines before 2007 and the 1.4 FSI. Opt for a classic 1.4 16v (80 hp) or the rare but excellent 1.6 16v (105 hp) on a phase 2 (9N3). For diesel, the 1.9 TDI is a longevity monster, but be aware of current traffic restrictions (Crit'Air). The purchase is recommended provided you target the right versions and check the history of the running gear.
