Nice place
Nice place. This is a nice place to find a car a lot of choices and the staff was so very helpful in my car buying adventure. I usually hate having to buy a car. Almost painless.

Customer
The experience was pleasant. The salesman and everyone involved made put forth the effort to make sure that I was comfortable with my purchase. The salesman, Guy, even drove the vehicle to my home to make sure it was the type of vehicle I needed for my husband who has difficulty getting in and out of cars. I appreciated that.
2021 GMC Sierra Denali

I had a top-notch car buying experience at Lamarque Ford!
I had a top-notch car buying experience at Lamarque Ford! My salesman, Kyran, was awesome?super down-to-earth, knowledgeable, and very patient throughout the entire process. The financial aspect, which can often be stressful, was also smooth and straightforward. I would definitely buy from Lamarque again in the future. Absolutely love my new Bronco Sport!!!
Great Buy!

I drive from Hammond to Ponchatoula (it?s only a 3 mile drive for me) because instead of taking my truck to my local ?big? dealer - I?d rather spend a few extra minutes driving to the Hometown style Ford dealership in Ponchatoula because they take better care of my needs than the larger dealers do!

Amazing experience!
Amazing experience! Everything was transparent no surprises, was worried about the long drive and having the dealership change things up on me but no everything was perfect. My sales man really is a down to earth gentleman, he went above and beyond for me and really hit a personal level of trust! Kimble wright is a name I will never forget based on my experience at this dealership.

Pleasure to do business with
I bought a 2011 Camaro SS from here Sept 2022, and I couldn’t be more pleased with my purchase. As a younger man (22 years old) I usually don’t get treated with as much respect and courtesy as older gentlemen do. Off the bat they were respectful, open minded, and overall a pleasure to do business with. I couldn’t be more happy with my purchase. After being lowballed for my 2020 Honda Civic trade-in or cash offer, I had 2 offers at a fair price and almost sold my car before visiting Danny here at Wholesale Auto. He beat the best cash offer I had for my car and got me in my beautiful red Chevrolet Camaro. Her name is Sally!

Jason Payne definitely made the purchase process the easiest! My husband recently had back surgery, so we were able to do everything very quickly, all we had to do was sign papers when we got to the dealership!! We were at the dealership less than an hour! We will definitely be doing business with Jason Payne in the future! I LOVE my GMC Terrain!!!
