odd they should say it's similar in size as the Kona is much smaller (164") than the CX-30 (173") - that's quite a difference! The Kona is about the same size as the Kia Soul.
The all new Kia Seltos and Nissan Qashqai is a better direct comparison to the CX-30.
"The 2020 Mazda CX-30 starts at $23,000, with all-wheel drive costing an additional $1,400. It costs slightly more than the $21,940 HR-V and $23,155 Crosstrek, with that last having standard all-wheel drive, but it does undercut the $24,335 Rogue Sport. Given the choice between all of those...
not exactly a glowing review by CR on this model giving it an overall score of 61.
For comparison on overall score some other ratings:
Subaru Crosstrek - 85
Hyundai Kona - 78
Nissan Rogue Sport (Qashqai) - 78
Mazda CX-3 - 73
Honda HR-V - 66
