It has fantastic gas mileage, it is very aesthetically pleasing (in my not so humble opinion), I find it fun to drive. It is also a sport hybrid, so acceleration pickup is actually just as good as other non hybrid sedans I have driven, even better than some.
It only has two seats. It is a pro for now, but I won't be able to keep the car when I have a kid because I can't keep a car seat in the front seat. Another con is not of the car itself, but that they discontinued making the vehicle making future repairs potentially harder.
The 2013 Honda CR-Z has an average owner rating of 4.71 out of 5 which ranks it #5 of 27 other Hybrid & Electrics.
