PLEASE, DO NOT GO TO OC NISSAN of GARDEN GROVE, CA for anything (ie. buying a car, getting service maintenance for your car, etc.). I DO NOT RECOMMEND OC NISSAN OF GARDEN GROVE, CA TO ANYBODY - ESPECIALLY MY FRIENDS AND FAMILY, SO THIS MEANS TO ALL OF YOU, TOO! I bought a car from them and I was treated badly, without Integrity and Ethics (they say they have high Integrity and Ethics - this is BULL CRAP!), and they damaged my car in so many ways (broke my front window, scratched my odometer's window and doors, dirtied my car with black stuff, dented my tire's metal thing - making my car lose tire pressure every month, dented the side-bottom of my car, and yelled and lectured me about Nissan of Garden Grove's Integrity and Ethics after losing my personal belongings). I told them about this - they didn't care and said that they do no such thing. They only fixed my front window because the damage was too big to be ignored. Also, before I bought the car - my mind was set on a different car with cash back on it - the sales person told me to buy another car because it has the same amount of cash back on it, so I did. THE CAR THAT I BOUGHT DID NOT HAVE ANY CASH BACK VALUE AT ALL! The sales person told me that the INVENTORY PRICE is the SAME as the MSRP (MANUFACTURE'S SUGGESTED RETAIL PRICE) - SO NOT TRUE! Also, I was denied a print-out copy of the INVENTORY PRICE - people, please know that if you ask for a print-out copy of the INVENTORY PRICE - you should get it (they shouldn't deny you). Also, I was promised a whole year's worth of free oil change (no matter how many times I brought my car in for the service) - THEY LIED! I ONLY GOT 4 FREE OIL CHANGES IN TOTAL.

The shop is very clean, friendly help, and did the repair needed to pass my vehicle's smog inspection. Thank You! will be back
