Fiat is an enormous Italian conglomerate that includes all of the Chrysler brands in its portfolio. The Fiat brand was reintroduced in the U.S. in 2011 with the diminutive, retro-styled 500. Despite attractive looks and a fun driving experience, various crudities limit its appeal. The 500L proved unimpressive in our tests. While the 500X is stylish, it likewise had a rather mediocre performance in our testing. The one bright spot, the engaging 124 Spider, has been discontinued. The limited data we have on Fiat shows that reliability and owner satisfaction remain quite low.
