I was a first-time buyer and honestly didn’t think I’d be able to get a car, but Nick did everything he could to make it work and truly went to bat for me. David made the signing easy and enjoyable — he had everything set up and kept the whole process stress-free. I’m so happy with my purchase. I’ve worked hard to get where I am, and this truly made my Saturday. I definitely recommend Autoline Pre-Owned!

I recently bought a car from Autoline Preowned and I had an amazing experience at Autoline Preowned!!! I’ve been to a lot of dealerships before, but this one truly stands out all of their employees was so helpfull and friendly, especially David Raines took great care of me from start to finish. He was friendly, honest, and very patient answering all my questions. The whole process was smooth, fast, and stress-free.If you’re looking to buy a car, I recommend Autoline Preowned, and definitely talk to David Raines. He’s one of the best I’ve ever deal with...

I had such an awesome experience today! They’re super nice and quick, and make sure everything is explained to you very well. So happy I chose to go with them! Jeremy and John are the best!

I sold my car to Autoline and it was the easiest, most pleasant experience from the moment I stepped in the door. Super friendly, honest and helpful staff. I am very happy with the outcome and they are happy with a very well-kept and clean 2024 vehicle added to their inventory. The whole thing took less than an hour. The space is comfortable with coffee and water and places to sit. Good music and welcoming atmosphere. I will definitely go there first for my next car sale needs, and I recommend them to anyone. Thanks to David, my primary point of contact, and to the other guys there who gave me a ride home, showed me how to make a pumpkin spice latte in the coffee machine, and made me feel so comfortable in the process!...

I was really nervous and reluctant about buying a car — it’s such a big decision and I didn’t want to feel pressured. From the moment I came to Autoline, the experience was completely different than I expected. There was absolutely no pressure, and everyone was so kind and helpful throughout the process. They took the time to answer all of my questions, made me feel comfortable, and helped me find the right car without any stress. I’m so glad I chose Autoline, and I’d highly recommend them to anyone who wants a smooth and honest car-buying experience! THANK YOU DAVID!... More

I truly appreciate the transparency and professionalism from start to finish. Highly recommend Autoline to anyone looking for a reliable vehicle and top-tier customer service! Brandon and David was great!... More

This is the 4th car I have purchased here at Autoline. Just walking in the front door, the smell of the lobby will make you feel like “this is home” The vibe is always on point. Jeremy always goes above and beyond as well as the rest of his team. David helped me understand what “independence day” meant to me, being today is Independence Day. (Insider) I’ve been without my own vehicle for 2 years now and they made this process fun and painless. I wont buy anywhere else but Autoline! Thank you Autoline for being so freaking awesome!!!...

Great experience with Brandon, David and Jeremy! I purchased a Subaru for my son, as a surprise for his birthday. Everyone at Autoline was friendly and helpful and went above and beyond to make sure that my son had a great experience. Highly recommend these guys this is my second purchase with them.

I want to express my gratitude to Autoline for my wonderful experience. I couldn't have asked for better service. My friend Nick, who works there and runs with me at Neptune Run Crew, referred me to this dealership. I had the chance to meet Jeremy, who treated me like family, showing me respect and patience. David helped me finalize the deal, and I left feeling happy. Autoline gave me the opportunity to drive my dad's favorite car, which he had asked me to buy before he passed away. Now, I can honor his memory by driving this special car.... More

Best car buying experience ever! Branden, Jeremy and David made for a seamless and pressure free transaction. Even the detail guys did a great job getting my new truck cleaned up and ready to roll. This is definitely the place to buy your next car.
