Customer Review
My experience at Certified Headquarters has been nothing but 100% satisfaction. From the sales to the financial aspect of the purchase they work with you to make sure you're a happy customer. The sales staff makes sure you understand each option you hae to match your individual needs. They answer all your questions & definitely are not pushy. Brian (Mgr.) with his years of experience is a person you can trust because he has so many years of training in his field. Jay in finance makes sure you understand the costs & makes you comfortable with the final total. I have referred my friends to shop at this reputable dealership & they've all been totally satisfied. You're in good hands at Certified.

Happy Couple
We would like to thank the staff at Certified HQ for an amazing experience. My husband and I recently purchased a 2010 BMW. Brian, Matt and Christina are wonderful, we highly recommend this dealership. We felt very comfortable from the moment we walked in. Never any pressure, and there were even a few laughs along the way! You guys rock!! 🙂
Satisfied Parent
I just had the smoothest experience I ever had in buying a car. If you are looking for a great vehicle Certified Headquarters is the place to go. Amongst the other standards that I had, I told them most importantly I was looking for a safe car or truck as I have a two year old child. I feel very confident that I found the perfect vehicle. As soon as I sat in it to take my test drive, I asked for the keys. Little to my knowledge, it was already running! Literally a smooth experience from the start! I'm so pleased with the price and how it fits right into the budget I told them I had to work with. Next to safety, this was the second most important concern of mine. I couldn't be happier! I can't begin to thank you enough Brian Smith and Lou Argerakis! Life can get stressful enough, thanks for making everything so easy. I love my Toyota Highlander! You guys are truly the best!
