Good Experience
I had to get a car in one day. A terrible pinch for the dealership. They rose to the occasion with kindness and honesty and had me out-the-door with a great deal before 2pm. Thanks especially to Delane Sheppard and Levi Durst. You guys made a difficult day easy!

After looking for weeks at Toyota RAV4's (used), I
After looking for weeks at Toyota RAV4's (used), I thought I found the one I wanted at Covert. Less than a mile into the test drive I knew it was NOT! My sales consultant, Tony Favors, was extremely helpful & showed me another used Toyota. Again, it didn't feel right. Instead of getting frustrated with me, he asked if he could make a suggestion, of which I was grateful. His recomendation led me to "the perfect car" for me...and it is NEW. Tony was attentive, intuitive, thoughtful, patient, thorough & a joy to visit with. His positive (genuinely caring personality) is a tremendous asset to the Covert Team! I will absolutely recommend him to anyone... 5 Star PLUS Tony!! And a shout out to Brandon who handled my paperwork (financing) for being equally patient & a pleasure to visit with. I couldn't have asked for better from either of these gentlemen!

We bought a LYRIQ this weekend.
We bought a LYRIQ this weekend. Our salesman was Martin He was awesome in his knowledge of the EV we purchased. It was delivered by Martin Saturday evening. Sunday morning we couldn’t get it to start(our stupidity) not knowing it starts when you don’t even it’s started. Martin was kind enough to come over Sunday morning to help us. We were so appreciative. Also “Coach “ gave us excellent info on how the car operates and help w getting a charger put in our garage. In the end we were extremely satisfied. So 5 out of 5 stars !!!
