2015 Chevrolet Sonic — Should You Buy One?
Typical asking price: $6,000–$10,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.
Kestrel Take
A peppy little subcompact — especially with the 1.4L turbo — that's more fun than a Versa but comes with GM's small-turbo maintenance list. Coolant leaks and turbo/PCV issues are the watch-items. The naturally aspirated 1.8L is simpler and less troublesome. Fine cheap transport if the cooling system checks out.
