Jake was my sales rep and he was very good to work with. He really is conscientious about making you comfortable to ask questions so you drive away a satisfied customer. Carlos, the manager, worked with me until I was comfortable with the deal. Highly recommend.

I recently purchased a used vehicle from Imperial. the salesman Gabriel Borrero was amazing. I told him my finance limit and he did not try to sell me a vehicle I could not afford. Ahmad Al-jallad worked for 2 days to get me financing with my low credit score. They will be my go to dealership from now on.

Van Horn is a Wow!
I dealt with Van Horn on an SUV for about a week. The vibe was so good that I ended up driving 900 miles on a Tuesday to make a purchase with them. I buy a lot of vehicles and I have never seen people stand behind their vehicles with such customer care and loyalty. They will earn your businesses.Very, very impressed and happy with their first class service and amazing warranty. I highly recommend Van Horn Chevrolet and their sales team.

I came to Honda of Fort Myers to look at a vehicle and was kindly introduce to Travis. He truly was a wonderful salesman to work with. He took his time and povided great knowledge and support without putting pressure to buy. He made sure to walk me through the process best as possible. That being said. Other team members were not so great with the financial negotiation. At one point she literally almost talked me out of getting the vehicle. I felt like it was being interogated for my choice in getting the vehicle. I truly wanted to walk away but to Travis's credit and his great approach at handling customer service i decided to push through it. I have dealt with many car salesman and Travis truly is a major asset to Honda of Fort Myers. They received a sale all due to him and his guest service skills. This man deserves a raise or a manager position. He can definitely make the dealership grow in a positive way.
