The Frontier has a lever hand brake in the console, easy to use while keeping both feet free and not impeding entry and exit. The Colorado’s foot pedal parking brake is not handy to use as a hill holding device with a manual transmission.
The Frontier V6’s optional dual zone air-conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Colorado doesn’t offer dual zone air-conditioning.
