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!!!

Our experience with Chapman Ford of Horsham was our
Our experience with Chapman Ford of Horsham was our second time dealing with a Chapman Auto Group Dealership. Both experiences were fantastic! We placed our order with Ashlie for a 2024 Ford F150. She was very helpful throughout the process and kept us up to date on our order status. Once the truck arrived at the dealership, we worked with John to get the lease deal figured out. He was very responsive and knowledgeable. When we arrived to pick up the truck, we worked with Liz who also handled our Grand Cherokee pick up and is always a pleasure to work with. Steve in sales helped to find a last minute offer from Ford and saved us some additional money on the truck which was very much appreciated! Finally, Kyle assisted in finalizing the financing. He was very knowledgeable and efficient and was able to answer any questions we had. The process was very quick but did not feel rushed. Overall, our experiences with Chapman dealerships have been nothing short of exceptional. The dedication and professionalism of Ashlie, John, Liz, Kyle, Steve, and the entire team show their commitment to a great buying experience. We have full confidence in recommending Chapman Ford of Horsham to friends and family, knowing that they will receive the same outstanding service that we have experienced firsthand.
