Well ... Cargo space is horrible.
To be honnest, price is a little bit higher than it should be (GT model starts at $30,000 CAD - almost the same thing as the CX-5 GS).
Erogonmy could be a headach to people that are more than 6 foot 3 tall.
In fact, if you don't need much space, are ready to pay for it and feel comfortable in it, it's a great vehicule.
Even if it's only a 2.0L engine, the weight make you feel you drive something more powerfull that it should be.
Just saying, my friend bought a HRV recently and admit that the CX-3 has a better looking overall, exterior/interior, with the 18 inches wheels.
The only reason why he took the Honda, it's because this is his only car, so he needed more space.
As a second car, I pretty much like it !
