I'm always pleased with Mossy, but this time they went beyond all expectations. The issues I had with my vehicle was very challenging, but Mossy never gave up (a BIG THANKS to Jeff, he's the man).

After moving to Northshore I found myself needing a larger, higher vehicle! I will say with all honesty I absolutely dread buying new cars! As an older lady I feel that I’m a target for an “easy” sale! My daughter recommended Honda of Covington! In all honesty from the moment I sat down with Mr Beck I felt totally at ease and completely comfortable with all parts of the process and everything he presented to me! He was very genuine and gave no pressure at all !! The dealership itself had a very friendly and relaxed feel ! I decided on a Honda CRV Exl.. It’s perfect!

Great service
I have been going to this dealership for over a year now and have had good and bad experiences. One thing I can say is that is something goes wrong like they will work hard to fix it and make things right. I would recommend this dealership to anyone. Like any dealership you will have good and bad but I think they appreciate the business and work hard to show you that.
