Top-Notch Customer Experience
I can not say enough about my experience at Long Cadillac. I was referred by a friend that has worked with Long over the past several years; his referral was nothing short of spot-on. The atmosphere at Long sets the gold standard for what every car dealership should strive for. My Sales Associate, Ron, greeted me with a smile and was eager to answer my questions. He was extremely knowledgeable and took the time to understand exactly what I was looking for. During our visit, we were also warmly greeted by Tom, the Sales Manager, who solidified that we were truly in the right place. On the day of pick-up Ron remained in contact with me to ensure a seamless transition. When I arrived at the dealership he had the car ready and was excited to go over every inch of my new vehicle. Even after leaving Long, the experience hasn't ended. Ron has remained in contact with me to answer any additional questions and to ensure I?m completely satisfied. All any customer wants is to feel valued and listened to; Long Cadillac certainly drove those feelings home. They deliver a top-notch customer experience and have certainly gained a lifetime customer in me!

I recently purchased a Jeep Wrangler from Dan at Drive
I recently purchased a Jeep Wrangler from Dan at Drive Automotive, and I couldn’t be happier with the experience. Dan has a great eye for quality vehicles in the market, and his no-pressure sales approach made the process smooth and stress-free. Not only did I get a fantastic deal, but he was also a great resource in navigating everything from start to finish. You can tell how passionate he is about cars and his customers—he went above and beyond to ensure the vehicle was fully detailed and that I drove off the lot with complete confidence, knowing there was nothing else I needed. I highly recommend working with Dan, and I definitely plan to do business with him again in the future

We had a great experience at Imperial Toyota working with Majed and Eric. They were friendly, very helpful, and didn’t pressure us into a purchase. We gave them some specs and walked away with exactly what we were looking for! We’ll definitely be going back for all of our services and future car purchases.
