My gf and I actually test drove the Kona immediately after test driving a CX-3, on a whim. We went to a Mazda dealer to test drive a Mazda3 hatch, tried out the CX-3 while we were there, and were so impressed we opened our minds to the subcompact CUV category. Then I mentioned that if we're looking at them, we should check out the Kona... and there happened to be a Hyundai dealership next door.
Long story short, after having driven the CX-3 moments before driving the Kona, the Kona is better in literally every way (unless you really have an issue with its styling.)
Love to see that folks are trading in their CX-3's for these, haha!
