About J.P. Gwinn

I'm a car guy! Over the last six years, being your trusted advisor, during one of your most important buying decisions, a car to suit your personal or family needs, has been my business. My passion for cars, however, started when I was twelve. I have always been in the customer service industry and had many years to perfect the way I work in customer service. Through all those years, I have learned to personalize all orders and services based on one single customer and not a general population. I want to truly serve my customers to the best of my ability. I will stay with customers until they are fully satisfied.

​Customer Reviews

JP has helped me and my late father with vehicle purchases and services from Greg Lair several times.
He is always very courteous and is very accommodating to people as he interacts with them. And he always tries to connect with everyone on a personal level it seems...that has made my experiences in working with JP great. If you need a vehicle that is affordable to you, go ahead and have a sit down with JP, he’ll take care of you.

Greg lair knows how to treat their customers with respect and dignity! They listen to your needs and allow you time to ponder on what your next choice is. They are friendly and professional. Go see for yourself! Go see JP and I am sure you will have a good experience!

What a pleasant surprise to walk into Greg Lair, and be treated as a person. From the minute I walked in the dealership, through test drive, and working to an agreeable price, I felt I had made the right decision, my sales person JP Gwinn, was outstanding, and professional, and patient explaining all the great features on my new LaCrosse. Just today I had a small issue, brought it by Greg Lair, took it into there service Dept, with no appointment, talked briefly with their service Manager, he said, it will take a few minutes, was I surprised when within 15 minutes, they said my car was ready. Thank you, everyone at Greg Lair, you reinstated my faith in General Motors

Thanks for the great experience. I love my new Buick Encore. This was the best car buying experience I have ever had. I really enjoyed meeting Mr. Lair, the salesman JP really knows his stuff. I will be coming back for more Technology Lessons. You really do Win with Gwinn Thank you JP.

I've known who JP is via social media and having met him at a few functions. Well, it turns out the social and laid back JP is the same as the salesman JP. JP is knowledgeable, friendly, honest, and fair. He sold me the truck I wanted. I had done my research but JP still told me things I did not know but sure needed to know. This is my second vehicle from Greg Lair and I most certainly will go back and see JP when the need arises. All of the folks I encountered at Greg Lair have been courteous, respectful, and very nice. It's a great dealership.

I had a WONDERFUL experience with JP Gwinn and the team at Greg Lair.  I hate the car buying process as much as anyone if not more than anyone.  These guys are fair and tend to business.  JP is the best salesman I have dealt with in my life.  He is nice and polite, courteous, thoughtful, sincere, very knowledgeable and willing to go out of his way to help his customers.  I am also going to say that he is honest, which is not a common description of car salesman.  Give these folks a chance to trade with you.  I will be returning to this dealership again for future business.
