The torsion-beam rear…
The torsion-beam rear suspension, lack of ventilated seats, lack of power passenger seat, and lack of power folding mirrors made the CX-30 a non-starter for me. Clearly Mazda limited content in these cars to push people towards the CX-5 and CX-50 - and it worked for me. I’ve had my ‘19 CX-5 turbo for a year and a half.
Still like the 30, just not enough to own one.
