Fiat Seicento.
What to Check Before Buying.

The Fiat Seicento is a compact city car built from 1998 to 2010, popular as a cheap runabout and first car. Its small engine and light weight make it economical to run, but age means most examples have racked up significant mileage and wear. Buyers should expect typical issues with older budget cars, including rust, worn suspension components, and neglected maintenance. Given the low values today, many Seicentos have been maintained on tight budgets, so a thorough check is essential.
