The Car Connection's Take
TCC Rating
6.0
5.4
TCC’s Bottom Line
The 2018 Chevrolet Sonic remains a good choice among subcompacts, though it’s now aging and losing some luster. New-car buyers seeking the comforts of a factory warranty can be limited in budget picks. The 2018 Kia Rio does many little things right for not a lot of cash.
