I had a such a wonderful experience purchasing my 2021
I had a such a wonderful experience purchasing my 2021 bmw x6 in January. I had no plan of getting the car I thought I was going to experience another rude salesman’s so I was just going to see it in person and really didn’t want to talk. I was totally wrong. Jayson was amazing and very professional. He had lots of patience with me. Jayson’s energy was amazing, so much so where due to unforeseen circumstances I was shopping for another car.. Since I had such a great unexpected experience with Jayson I said I have to go back to him even though the dealership is 1 hour and 15 minutes away from me and I was referred to another dealership 15 minutes away from me. I called him and said Jayson let’s make magic again after telling him what I was looking for.. Well yesterday that was what we did. I purchased a 2023 bmw x6 with the M sport package (my white diamond) Jayson once again was simplyyyyyy amazing, alone with MrJR, one of the managers, Mr. Bobby another manager and Mr. Don the finance manager. Thank you guys so much.. Jayson was a call away and talked to me while he was off.. I told Jayson I wasn’t taking that drive to the dealership unless we could make magic with that car, he said don’t worry we will and we DID💃🏽 Another great experience . Wonderful people who made a horrible experience turn into an amazing one that was worth the drive anytime.. Looking to get a car definitely ask for Jayson Robertson, he is truly that guy!! I’m a loyal customer because of him I took that drive to the dealership because of him Im writing this review because of him…Jayson thanks again for making magic , you rock dude!!!

Our salesman, Landon Crane, is new and even didn’t have
Our salesman, Landon Crane, is new and even didn’t have his business cards yet but he’s gonna go far. He was extremely polite, willing to answer questions and had no problem getting up to ask about an answer he wasn’t certain of. I appreciated he wasn’t pushy, condescending, or fake. He may be young and just getting started but you won’t go wrong by requesting him for your salesman. The young man knows how to give an appropriate handshake on top of all his other positive qualities. From start to finish it was a relaxed buying experience. Give him a call!
