I had an outstanding experience purchasing my BMW X5 at LSM CARS thanks to Shawn's and Mike's exceptional service. This has been my second experience working with Shawn, and once again, he was professional, knowledgeable, and genuinely attentive to my needs throughout the entire process. Shawn made sure I understood every detail and helped me find the perfect X5 configuration. His dedication and warm approach makes me feel like a valued customer from start to finish. I highly recommend Shawn and Mike to anyone looking for a smooth and enjoyable car buying experience!
Better than my old truck

Caesar Quintero Always make it happen for us!! He provided great service and insight in purchasing our vehicle.
This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

Much Better Than Expected!
Much Better Than Expected! Worth the Drive. Purchased a 2014 Toyota Sienna I drove several hours to this dealership to check out a specific 2014 Toyota Sienna—and I’m really glad I did. My salesperson, Chris, was outstanding from start to finish. He was extremely responsive, easy to work with, and genuinely honest. He answered all of my questions quickly and clearly, and was very personable without being pushy. The car was exactly as described, and the buying process was smooth. A day after I brought the Sienna home, the check engine light came on. I was obviously concerned since the sale was already finalized, but Chris immediately told me to bring it back in. The dealership diagnosed it as a faulty sensor and replaced it on the spot with OEM parts at no cost. That kind of post-sale support is rare, and really impressed me—they stood by their product 100%. One thing to note: there are dealership fees totaling about $1,400, which in my case were not negotiable, HOWEVER, the fees do include services like LoJack protection and a paint/interior protectant, so there’s actual value provided—not just markup. Also, if you look at the bottom of the ad, the dealership does mention that they are included. Overall, I’m very satisfied with my experience. The car is running great, the team was professional, and Chris went above and beyond. My experience was much more positive than the online reviews led me to expect. If you're considering buying from this dealership, I highly recommend reaching out to Chris!

I called the dealership and spoke to Gary Koch.
I called the dealership and spoke to Gary Koch. I found him to be very personable and knowledgeable. We discussed the online price and agreed to purchase the car. I am not local and handled the preliminary paperwork over the phone. Once everything was confirmed I booked a flight and Gary offered to pick me up. I was in and out of the dealership in less than 90 minutes. Gary made the car buying process super easy and enjoyable. I also received an exceptional deal.
