The second-generation Toyota Prius (XW20) is the model that truly popularized hybrid powertrains worldwide. Recognizable by its aerodynamic "teardrop" (Kammback) silhouette offering a drag coefficient (Cx) of 0.26, it introduced the second-generation Hybrid Synergy Drive (HSD) system. Praised by taxi drivers for its exceptional reliability and low running costs, it is now considered one of the most robust cars of the 21st century. A slight restyling (facelift) occurred in late 2005 / early 2006, bringing finish improvements, recalibrated suspension, and a multimedia system update. Expert's overall note: A monument in automotive history, whose mechanical longevity is exceptional, but which now suffers from its age (battery wear) and an external scourge (catalytic converter theft).
The Toyota Prius II is an icon of reliability. Buying this model used today is still an excellent idea for those on a tight budget looking for an economical car, under two strict conditions: 1) Ensure that the high-voltage battery has been recently replaced or is in excellent health. 2) Absolutely protect the catalytic converter against theft (or verify that it has already been secured). If these two points are validated, you're good for hundreds of thousands of kilometers.
