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.
This truck has a jerk when changing gears sometimes.

Being an out of state buyer makes buying a new (to me)
Being an out of state buyer makes buying a new (to me) car slightly trickier, and I will say that Dave and crew at Peruzzi Toyota did a more than fantastic job! Every step of the process was as painless as could be, from first inquiry (cars.com) to some initial questions, to asking for a few additional photos. Everyone was very attentive, responsive and happy to help! I'm beyond happy with my new ride!!!

Great Service , People and Cars
I have to say that this has been the best car buying experience ever! I went in and my sales consultant, Nakia Scott, was very friendly and patient. Even before I got there, she was very helpful over the phone. The car selection was just great. The quality of cars there is unbeatable. Every car has a perfect Carfax as well. The entire process from walking in to driving out was less than 2 hours and I left with a better finance deal than I had when I walked in. The car is excellent and they warranty is the best. Oh and I got my registration transferred and it's only been a week and a half and I already received my updated one in the mail. I have no complaints. Extra set of keys, full tank of gas, great warranty and a like new car. Love this place!!!
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

best all round dealer
I personally own 10 cars including a Ferrari and Bentley. I love my Shelby Mustang. John Kennedy Ford treats me even better than the "high end"dealers! Kevin Stuski is the man to ask for when you go

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!
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!

Very smooth buying.
I’ve recently bought a 2023 Yukon from star. I made a appt with Colleen to see the car. When I got there I was greeted by her and then she introduced me to Kyle. He walked me right up to the car a had the appt on. Keys were even in his hand so I didn’t have to wait. I took it for a drive and fell in love with it. He knew the Yukon in and out. Then when it came to financing the car Justin in finance made it very easy. He gave me a couple options to make sure I was covered if I wanted. Out of every car I’ve ever bought (I’m almost 50) I’ve never been so relaxed start to finish with my purchase. I’ve even been back to ask questions on things I’ve forgot and never had to wait to get an answer. You can definitely tell this dealership is family owned . Way to go team. Thanks Star of Quakertown

A big thank you to Dom, Heather, and the financing team
A big thank you to Dom, Heather, and the financing team at Star Of Quakertown. They made my car buying experience just wonderful. They went above and beyond to get me my vehicle and I'm so happy with it. Even thought they were an hour and a half away from me, they were just awesome. Very welcoming and I definitely recommend them. I'd drive another hour and a half to get another vehicle from them. Great job guys! Keep up the great work!!

Brought my son's Acadia in because one morning it would
Brought my son's Acadia in because one morning it would not shift into reverse and the CEL came on. It seemed to fix itself as the CEL went off. I brought it in anyway to be sure as it did show two codes. Eric and his team thoroughly checked everything possible for a day and a half and determined it was fine but he wanted everything well documented in case it happened again and it was out of warranty. They never were able to get the CEL on while at the shop after driving it for a bit. Great work by Eric and the tech's who worked on it.
