Audi A2 I (8Z) (1999 – 2005)

Reliability score : 7.8/10

The Audi A2 (Type 8Z) is a premium versatile city car that was far ahead of its time. Designed around the all-aluminum ASF (Audi Space Frame) technology, it boasts a featherweight (often under a ton) and exceptional aerodynamics (Cd of 0.25 to 0.28). Although shunned upon its release due to an elitist price and a polarizing design, it is today a highly sought-after youngtimer. Its total lack of corrosion (aluminum) and remarkable roominess make it a durable used vehicle. The petrol range, although limited, offers blocks from the Volkswagen group's parts bin (EA111 family), with undeniable qualities but some chronic defects to monitor. Overall expert rating: An engineering marvel, economical to run, but whose bodywork repairs and certain equipment (Open Sky roof) can be expensive.
