Great dealership and great sales staff
I called and inquired about a used Ram truck to confirm it was still available. Alma Turner contacted me and confirmed it was still there. I made an appointment to go in the following morning and met with Gage my salesman I test drove the truck, and it exceeded my expectations I proceeded to make my purchase and all of the staff that I had dealings with were professionals and courteous I highly recommend Gage, and this dealership, if you are looking to buy a vehicle

Working with Ethan on my 1st ever online purchase
Working with Ethan on my 1st ever online purchase - was the 1st experience everyone wants! He was efficient with communications, but never pushy. He was flexible and open to any questions, while walking me through the process! Friendly, knowledgeable, and great to work with. The financing process with David's help was a breeze! The process was time efficient and pretty flawless. He was on point with communication and very knowledgeable. Still loving my new car 2 months later- it exactly what I wanted and drives like a dream!!!

I recently purchased a vehicle from Top Line Auto, and the experience was outstanding from start to finish. The team was incredibly knowledgeable, attentive, and genuinely committed to making sure I found the perfect car. They went above and beyond in providing detailed information about the vehicle, including mileage, Carfax history, and available warranties, which made me feel confident in my purchase. The process was smooth and stress-free, with no pressure or rush to make a decision. I also appreciated their willingness to work with my schedule and accommodate my needs. The level of customer service at Top Line Auto is truly exceptional, and I would highly recommend them to anyone looking for a quality vehicle and a hassle-free buying experience.
