The entire team at this location far exceeded our expectations! Our sales consultant Sandi was extremely easy to work with, and he had our best interest in mind when working on a deal for a new truck. When it came time to financing, Alex ensured we got in and out with exactly what we needed. He provided us personal stories bridging to his recommendations that help guide my wife and I in a direction that surpassed what we originally had in mind. Finally, throughout the visit Edgar and Manny ensured we felt comfortable as we worked though a deal that would ultimately have us driving home without any doubts in a vehicle that can grow with my family. They were the cherry on top to an already excellent experience. Thank you from the bottom of our hearts for such a great team!

We came in late in the day with an unexpected emergency
We came in late in the day with an unexpected emergency car repair and were very happy with the service provided. Everything was great! Check in, our shuttle driver Vicky was so kind and even stayed late to take us home which we appreciated. The car was fixed in a short amount of time and shuttle driver back Ed also very nice. We've purchased and had our cars serviced from D'Arcy since 1990 and could not be more pleased! Thank you!
