Hi Emil,
I'm happy to help you find the right hitch for your Mazda3 GS!
I recommend the EcoHitch Class 2 because it has a concealed cross tube, so it's going to look much cleaner and more seamless on your Mazda.
If you have a sedan, the EcoHitch you’ll need is part # 306-X7303.
If you have a hatchback, you’ll want part # 306-X7305.
The only downside with the EcoHitch is that the installation is a little more involved — it does require removing the bumper. So if you're planning to install it yourself or prefer not to deal with extra labor costs, let me know! We can definitely look at some other options together if you'd like.
Also, just to be fully transparent, the wiring you’ll need ( part # 118405 ) is currently on backorder through us.
Comment below if this option doesn't work for your situation.

Hey Emil, did you decide to go with the EcoHitch for your Mazda3? I'm curious if the installation process worked out for you, especially with the bumper removal. Your experience could really help others considering a similar setup!
