I have been in Planet Nissan, multiple times, I was treated with RESPECT, so much so, I took my girlfriend there and she bought a Nissan Altima. Her Altima has been problem free (other than a small recall) and service treated her well. I did almost buy a car, however, changed my mind about having a car payment.
I can say the BDC dept. treated me good, as well as the GM Sam.
