We recently bought an Honda Odyssey from Emmons.
We recently bought an Honda Odyssey from Emmons. I like the standard of listing them below market and at their sale price. Saves the time spent haggling that you have with most dealers to find the sweet spot for both parties in their mark up. We had a small issue with the automatic rear hatch opening, they got right to work and had it fixed before we left. Overall a good experience and would recommend.

Great simple oroceds
Rees was my greeter and was an excellent source of information and sales expediter. Rees explained the CarMax process and then Listened to the car features I required. He did searches of car max inventory, searches of manufacturers’ sites for additional info, and requested transfer of a vehicle from another location. There was no pressure to buy (CarMax has a five day return policy). Paperwork was efficient, and I even got help getting both the car I bought and the car I arrived in home. It was my first solo car buying experience so I especially appreciated that I got a car that suited me at a fair price and no hassle
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Very good experience. To be or not to be, that is the question. Whether it?s nobler in the mind to suffer the slings and arrows of outrageous fortune or to take arms against a sea of troubles and by opposing end them.
2021 GMC Sierra Denali
This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

Kevin was great.
Kevin was great. He even moved our van into the showroom during that rainy day. Soon after that we had the kind of deal we were looking for. Then we started adding the accessories we wanted?. So a couple of those prices were higher than expected. Again, he brought the sales manager and they greatly reduced those accessories to make the deal. Facilities are great, service was great.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Very professional, great group.
Very professional, great group. Last Tesla I bought was purchased from a group that sells 50-65 teslas a month (idrive in Carrolton tx). Auto Boutique surprised me, and managed a Tesla sale like a group that sells 10x more of these technically challenging vehicles. They got the car added to my Tesla app quickly and I left the dealership able to supercharge and drive 6 hours to my home. The young guys ( Ethen Beck and Enrique Ovalles) were very Tesla literate. I'm a contributor to a tesla owners forum and have over 4 million content views, so I'm not a Tesla Newbie. I have a 2016 model s p85, a 2021 model y dual motor, and now a 2021 refresh model s long range to replace the aging ap1 car. These guys had the recurrent battery report in addition to the carfax so I could skip checking the battery. Staff went into service mode and we checked the error log. They got an update to post before adding the car and so I drove off in great shape!
