I moved to the area almost a year ago. Had a Ford that I took to a great dealership in Crane, MO. I totaled that Ford in January. When I went looking for a dealership to take care of my new Buick, I found Pearl on line. They had really good reviews. I booked my first appointment and was hooked. The people at Pearl are knowledgeable, considerate and friendly. I have had a better experience with them than my Ford dealer that I went to for 6 years. I highly recommend taking your car for service there. I’ll be back for anything my car needs. Thank you to Dayton, the mechanics and the office staff that are always so helpful. S. Moseley

I had a great buying experience in September 2025 and my first vehicle service in May 2026. The folks at Pearl Motor Company have been very professional, efficient, and pleasant to do business with.

DealerRater May 12, 2026

The May tire sale bonanza gave me some much needed inflationary relief. Pearl Motor Company beat the local area tire dealer's quote by a mile! I'd say it would be prudent to check with PMC before buying tires anywhere!

DealerRater May 12, 2026

Tony Allen really made my truck purchase fun and easy! I called about an F350 they had just posted on their website. Tony held the truck on my word that I would be there. Had a very enjoyable test drive and they got me in and out of there in a short amount of time. Certainly the easiest car buying experience I’ve ever had and can not say enough good things about my salesman! No pressure, comical, polite, just how sales should be!

DealerRater May 9, 2026
