Volkswagen Lupo.
What to Check Before Buying.

The Volkswagen Lupo was a compact city car produced from 1998 to 2005, offering efficient motoring in an agile package. Popular with urban drivers and first-time buyers, the Lupo earned a reputation for solid build quality typical of VW, though age means many examples now show wear. Buyers should pay close attention to electrical components and corrosion, particularly on older high-mileage examples that may have been used for short journeys only.
