Malibu 2022
Highly competent, professionally friendly sales person. Extensively knowledgeable about options and differences in models we saw. Very skilled at not pushing, but helping my wife and me come to a decision. In the top 5% of sales persons I have known over many years.
This truck has a jerk when changing gears sometimes.

Doug White was amazing He sold me my last car and was so
Doug White was amazing He sold me my last car and was so helpful again. The windshield in my new 2019 had a chip which I was told would be taking care of with a new windshield before I picked up the car. That didn’t happen. They sealed it and it was front and center to my view. I’m short. It rained most of last weekend and I hardly drove it. Then the sun came out. My friends all said what’s that in your windshield. Unacceptable. Then I was trying to make a time to bring it in for the replacement and the guy said we could rent you a car for $42 a day. Even though that didn’t happen why would I pay for a rental when you inconvenienced me by not doing the windshield before pick up. My friends were saying shocking. Tasca is a reputable business. Ok done venting. None of this is Doug Whites fault. Thank you

Got my certified Car Bravo Chevy Tahoe from Peter
Got my certified Car Bravo Chevy Tahoe from Peter Franklin. There was no pressure. I got a great price that cars.com confirmed ahead of time for me. Peter made sure it was the right car for me and the experience could not have been more pleasant. If you want a no pressure experience buying a car go see Peter Franklin at Herb Connolly Chevrolet.

Amazing place to buy a car
Amazing experience. I'd recommend anyone looking for a car to try CarMax first... There's zero pressure, tons of beautiful vehicles, and just an all around great place. Will definitely be buying from here in the future. They're willing to work with you if you don't have the best credit, and most importantly, they're just honest and transparent. Two very important things when spending tens of thousands of dollars. Put it this way, it was great enough experience for me to come online and leave reviews all over!

Midway Automotive
They were excellent. They got me right to the car I was looking for and They did not attempt to add any illegitimate fees to increase the price. They got the car ready for me so I could pick it up the next day ready to go. The experience of getting a car from this place went as well as it could have gone. I highly recommend them. The person who helped me was Frank Santino and he was easy to work with.
