Plenty of car for the price.
A great car with lots of features that come in standards which other brands don't. The car has plenty of horsepower compared to cases of similar build and price. Led lights us a big step up from the traditional bulb. The only thing I don't really like is the cladding around the car. They are too big, will have been nice if they had made it smaller.

Overall, I probably wouldn't get another Mazda after my lease is up.
Some problems on the car I have had since only having the car for 1 month is I had a 'safety feature disable get vehicle inspected' note on the dashboard with nothing affecting the car, I have also had another problem where I put the car in park and then to drive and the car didn't go, even after I tried multiple times, I had to turn the car off and then back on for the car to go and this happened in the middle of a drive thru! Other than that, some pros are the infotainment system-- very sleek classy look, apple CarPlay works fine as well as the heat system is another big plus for me.

However, for those looking for vast cargo space, the CX-30 might be a bit limiting, as its cargo capacity is on the smaller side compared to some competitors in the crossover segment.

For instance, you can easily fit in several large grocery bags, a couple of medium-sized suitcases, or outdoor gear like a compact tent and sleeping bags. This makes the CX-30 a versatile option for both urban commuting and occasional outdoor adventures.

Beyond the primary cargo area, the 2021 Mazda CX-30 also excels in offering numerous small storage spaces throughout the cabin, enhancing its practicality.

The thoughtful design of these storage spaces underscores Mazda’s commitment to combining functionality with elegant design, making sure that every aspect of the vehicle is both useful and aesthetically pleasing.
