14. Fiat 500L
The Fiat 500L has gained notoriety for its persistent reliability issues and lackluster driving experience. Its reputation for frequent mechanical problems and disappointing resale value make it an unattractive proposition for both buyers and thieves. With so few people seeking out the 500L or its parts, there’s little incentive for criminals to target this quirky hatchback. According to Consumer Reports, the Fiat 500L’s poor reputation serves as its best anti-theft deterrent.
