Jeremy, Nick and David as always were amazing. This is my 3rd car from them. I still have the traverse and Tahoe I purchased from them. I know when I buy a car from them it is a quality car that will last. This car is for my daughter. I am happy knowing she is in good hands and will remain safe. We were there less than an hour and were driving off the lot. I highly recommend them and will never buy a car from anyone else. Their reputation is top notch.

Great crew! Jeremy, Nick, and Randy were all excellent to work with! They are trustworthy, kind, and laid-back. We didn't have to worry about being pressured or swindled here. The purchasing process was professional and a breeze. Highly recommend these guys!

Totally painless experience! Great selection and everyone is wonderful! My daughter had gone there and said she was gonna go on her lunch break and I said that will never work because it takes too long and they promised her they would get her out quick and they had her out in 25 minutes! So when I needed a car, I knew exactly where I had to go, and I had a great experience!

Best car buying experience I've ever had. Nick and David really took care of me and treated me like one of the boys. I never felt any pressure, was the most chill car buying experience ever. I will definitely tell everyone I know to come here first. They also offered me top $$ on my trade in. Top notch experience. Top notch crew.Thanks for making this a great experience. Thanks for helping me get into this Tacoma!

The crew at Autoline made buying our car enjoyable, which is the opposite of our experiences at other dealerships. They say they strive to change the car buying experience to be a stress free and easy task and they are doing just that! They made it quicker and easier than I thought possible and made sure we understood every step. It felt like doing business with a friend, not a sales associate. I highly recommend to anyone looking for a vehicle!

My wife and I had the best experience at Autoline. We had our sights set on the 2024 Subaru Crosstrek Limited, they were the only dealership in town with a used, low mileage with all the features it included. And of course we fell in love with it. Nick, Brandon and David were super knowledgeable and easy to talk to. I came in with very low expectations from previous negative car dealership experiences, ready to go guns blazing tbh… but I found that I didn’t need to. I had a trade in and was given an amazing price (higher than the KBB and Carvana quotes I had brought in), and there were essentially no hidden fees and they do not pressure you into the extra warranty at all. Ended up walking away with a price lower than I was expecting. You will do no haggling here and the entire experience will be stress free. 10/10 recommend!!!... More

David &Nick were PERFECT!! I’ve never had a better experience at a dealership and if I could give more stars i would!! Shout out to Joey as well for getting us started and we will most DEFF be coming back!!

Was the best experience!!! Honestly took less than a hour to find the vehicle for me, credit check, test drive, and get financed... What was great was the hospitality from all the guys!! My wife spoke with Nick (perfect hospitality, helpful, understanding) on the phone before we arrived and he got us settled in once we got there, David helped with all the paperwork and signing (real professional, knowledgeable, and kind)... Everything was perfect!!! and there was a guy i forgot his name was awesome as well he know who he is :)... More

Nick and the whole crew were awesome. Best car buying experience we’ve had by far. There was no haggling and a fair value was given for my trade and asked for the vehicle I purchased. Definitely the place to shop if you want a human approach and to leave feeling no buyers remorse whatsoever. Future car purchases will be coming back and loved that they were longtime locals that know the same places and people that we do. Thanks guys!

Went to the dealer based on a strong recommendation and we live 8 hours away! Everything was above and beyond what was expected. These folks are honest, straightforward, and care more about you than the sale. They helped us figure out the best vehicle to meet all of our needs and accommodated our requests. They were patient and answered all of our questions. This is where you go to get car!
