Consumer Reviews for the Mazda CX-9
Read recent reviews for the Mazda CX-9
2021 Mazda CX-9 has all the room and luxury
KHix, 10/30/2020
2021 Mazda CX-9 Grand Touring 4dr SUV AWD (2.5L 4cyl Turbo 6A)
If you are looking for a lot of room, but not really looking for a vehicle to go 4 wheeling and towing a boat with, then the CX-9 is the car for you. We have had the car for a month now and talked to several previous owners of the CX-9 and they all recommend this car. We love all the options and the room. We opted for the Grand Touring, not the Signature because we didn't want the … console between the captains chairs in the 2nd row. We prefer the walk through. But we didn't lose any other options except for the Napa Leather....which is nice but the regular leather is nice as well. For that reason we couldn't see spending an extra 5K on the Signature version.
