Tried a few cars, they gave me the keys, I drove around
Tried a few cars, they gave me the keys, I drove around - no pressure, no hard sell. Picked a Ford F-150 and closed the deal without stress. The vibe felt normal, like hanging out with friends.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Great experience
My husband and I stoped by to look at a VW Jetta for our daughter. At the time, the car was not at this location. Lou made sure the car was there the next morning and we were able to take a look. Over the next few days, Lou was extremely patient with our hectic schedule as we completed the process of buying the car. My husband and I both agree, this was the best used car experience we have ever had, with outstanding customer service from Lou and his team. We would definitely go back the next time we are looking to purchase a car. Thanks Lou!

Erica from Miller sales beat every dealers out the door
Erica from Miller sales beat every dealers out the door price on a new truck and then told me she could beat my credit unions rate. She did by 2.5% and the manager gave me an extra 1000 off for financing through Ford AFTER I was approved at a lower rate. True sales lady that cuts through all the unwanted salesman tactics. Erica knows her job and is supported by an honest manager. Best car buying experience in 20 years and I buy a new vehicle every two years. Finding a service dept that is just as great was the icing on the cake. Mark had my truck prepped exactly as I asked when had my first service done. Miller w Erica has my family's Ford buisness from now on.

We recently purchased a 2003 Ford Thunderbird from
We recently purchased a 2003 Ford Thunderbird from Highline Motor Cars. Ali was our salesperson and he was very helpful. After looking around for this particular model, we found exactly what we were looking for. Ali gave us a good deal and was upfront regarding some routine maintenance the car would need. The car itself was in fabulous condition for it's age! We now have our "retirement" car to take weekend rides! Thank you to Ali and the crew for even offering us lunch! I was waiting for the weather to break (finally) to take a nice drive down the shore and we are in love! Thank you again Highline! We recommend your dealership for a good deal and honesty!

im not new to buying cars.
im not new to buying cars. ive owned hundreds and currently own 6 cars , 6 trucks and 3 motercycles. i however am new to the excellent service I received. Ill never buy a car from anywhere else. Bergeys team were the most knowledgeable and and easy to deal with ever. Then theres the deal part. no other place could even come close to what they came up with for me. if I had to describe everything in brief , " like a well oiled machine" When It came time to show me how everything works 3 of the Bergeys team came out. and all my questions was answered. I made the best choice ever Going to Bergeys GMC. The kind of place where you can stop anytime with questions and its not a bother
There are 20 matching cars close to your year range.
