Lease expiration options
Met with Anthony R. to discuss my upcoming lease expiration. He worked out all the options I had, and was very supportive. I also had to get my Jeep inspected at the same time. It was a very pleasant experience.
This truck has a jerk when changing gears sometimes.

Felt welcomed the moment we walked through the door. Knowledgeable staff, great prices, spectacular inventory. We found the car we wanted. Frederick helped us with the car, he is everything you want in a salesman. Frederick listened to what we wanted in a car, worked with our price range, he wasn’t that typical car salesman you always hear about, he was great, truly caring. We will definitely return to Autobahn USA when we need another car.

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.
Nicest, best performing truck I've ever owned

Of all the Toyota dealerships I visited, Dave Souza at
Of all the Toyota dealerships I visited, Dave Souza at Imperial Toyota was able to find the exact car I was hoping for (he kept looking long after we spoke in-person) and reached out when he found it. He was helpful, not pushy at all. …and I really like my RAV-4 Prime… it is so smooth and zippy to drive… and the supersonic red is extra fun.
2021 GMC Sierra Denali
This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

They are fantastic
I purchased a 2008 honda crv67,000 miles. I thought maybe I had no chance to get into this Honda because of bad credit. But they assured me if this is the car I want they would make it happen and sure enough it did. The next day I was in my car and very happy. They were understanding, caring, helpful. They made sure the car was in mint condition when they gave it to us. It is running beautiful. I am so glad I went there. I would buy another car there in a heartbeat. They were absolutely wonderful. Thank you car max for making are dreams come true.
