The Nissan Versa's climate control system is a good example of simplicity at its finest. Mercedes-Benz and BMW, with their fancy COMAND and iDrive central control systems, may have you thinking there's a better way. Don't believe it. Instead of burying functions within a confusing electronic setup or offering poorly marked miniscule buttons, the Versa offers three dials – one for fan speed, one for temperature, and one for airflow direction. That's it, basic and effective.
