Have the 21 the upgrades features like the 10 speaker stereo, chrome accents and front grill make it really stand out from the other models. Drive it sport mostly, it has plenty of pick up. I really enjoy it. Has 40k on it, kept up the maintenance and just bought 4 new tires lately. Bought used with 12k👍 - 5.0
Simple and reliable

I have had mine for about a year and a half and it’s just a good car. I’m the kind of person to sell a car after 2 years or so until I got my civic. There is just nothing on it that justifies me to upgrade. The sound system could be a little better but it is only an ex so it did not get the premium sound system. I like this car because it is fairly modern but not too modern. It doesn’t have auto start stop or any insane lane assists or sensors to beep at you. But you still get stuff like remote start and a pretty nice screen for android auto/apple car play. Some even had heated seats which I wish I had. This is the kind of car that as long as you do maintenance on, you will probably get to 200,000 miles with no engine lights or big issues. The only thing I will say is that the maintenance cost of the 2.0l will be way better than the 1.5T. If you want one to last as long as old Hondas, get the 2.0l and change your cvt fluid every 30,000 to 50,000. Other than that these are great cars and I definitely recommend it to people who want a mix of modern touches and a sporty look with classic Honda reliability. - 5.0

I got my car about 2 years ago. I haven't had any issues with her whatsoever in all that time. Because of the ease of ownership and work, I've been able to rotate tires on my own, change my own oil, and work on her in general. I don't have a single bad word to say about this car. One of the best selling brands in the world? Makes complete sense. She's a set it and forget it kind of car. Take care of her and she'll take care of you. That's all I need to say and all you need to read.
