I just came to scout the place and got a warm welcome. The manager didn’t hit me with a “how can I help you?” line - just came over and said, “Keys are right here if you want to check it out.” That’s exactly the kind of approach I respect.

I came across this dealership, Automotive Avenues, by
I came across this dealership, Automotive Avenues, by chance and I am so glad that I did! I was looking at different cars on their website, but it honestly looked like it was "too good to be true" price wise for the cars that they were offering. I started the process with Anthony, who is in the online sales. He was so responsive and right to the point. He was communicating with me even on a Sunday when the store was closed! I was still not convinced and I thought there had to be more to it. He was very clear about the "No haggle" policy, which I love, and told me specifically what fees they charge. I decided to drive from Harrisburg, PA (3.5 hour drive) based on all the information that I had. I was looking at FOUR different cars that they had. They were kind enough to offer to hold one of them for me. It is not what they normally do, but they gave me an exception till I got there, since I had a long drive. Once I got there, I was amazed by how busy the place was on a Monday afternoon and how many beautiful cars they actually had on their lots! I was greeted by Charlie Jackson, one of their 22 sales people. He introduced himself, asked me if I was working with anyone. I told him that I've only spoken to the online sales, but I had an appointment for 5:30. He took me inside to check in, asked me if I wanted water or coffee then took me to his desk where we sat and discussed each one of the 4 cars in details including their Carfax and any other information that the dealership had to share with me. He was very patient and knowledgeable! After that, he brought the cars to the front for me to look at and test drive (except for one because I was looking at all electric cars, and the battery was not charged in that one) so we walked to it just so I can see it in person. Once I saw all of them and test drove the 3 that I could, I decided on one ( which was so hard because I wanted to take the 4 of them home). The one that I bought was a 2022 Mercedes EQS 450+. It was like brand new with just over 1100 miles on it! It was the car that I really wanted from the beginning and I ended up getting at the end. After that, we worked out the numbers on my trade, which I was NOT very excited about because it was about $1500 less than what I got from others! I agreed to it and they started to process the transaction. They stayed with me till about 9:30 pm, way after they were supposed to close, just to accommodate me so I would not have to drive again the next day. I must say that I change cars every 6-12 months because I love cars, and (other than the trade) I've NEVER felt as good purchasing as I did this time. Thank you very much and I will be back for my next one soon. You are doing things right and it is worth the long drive for sure.

Great customer experience
Top of the line dealership. My team of team. Great family business. I would recommend to anyone. They had the Lexus LS ready for me as advertised. No behind the scenes cost. Straight to the point. I am very happy with my new car and overall customer experience. Can’t wait to buy my next Lexus. Ask for my man Danish.

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.

Our salesman, Will Oese, spent the day finding us the perfect vehicle. We spoke to him months before our lease was due, he was very knowledgeable and sent us different options. When we scheduled the appointment, we were only coming in to look at cars, but we had such an awesome experience with Will, that we left with a new car same day. We highly recommend Will Oese, Jesse Embry, Chris Tandy, and Claudia for all their assistance that day!

Overall, happy with the service.
Overall, happy with the service. Would have been 5 stars, however, my only complaint was the Parts Dept wouldn't match the discounted cost for 4 TPMS sensors. Originally they were charging $135 per sensor, while Chevrolet's website price was under $107 per sensor, which they did match. However, the online purchase was discounted by 20%, which would reduce the price per sensor to less than $87 each but they wouldn't match that price even though it said to pick them up at Burlington Chevrolet.

A surprisingly pleasant experience
Best experience I've ever had with a dealership service department! Michelle and Jack picked up my car and returned it to me!! Friendly, clean, pleasant and competent. So rare these days. I would recommend them highly, especially over Freehold Buick. Freehold Buick tried to rip me off on several occasions. They lied to me and were disrespectful. I'll never go back to Freehold Buick, but look forward to working with Jim Curley Buick of Keyport in the future. Thanks so much.
