Our Reviews
Very honest and great people to work with. Made a great deal and a great vehicle.
Great dealership & staff A+++++++++++++++++++++++++++++++++++++++++++++++++ stars, I have bought a few cars and lease cars from Boucher auto group for years
I was pleased how pleasant every one was..They sent a vidieo showing me what was wrong an estimate what the cost was going to be.
Electric and speaker issues within vehicle Bought brand new car and brought it back more 4 times .
I really like the videos that the mechanics send out with an explanation of what the problem was and the fix. Been treating me good!
Jain was communicative and shared what the issue could be. Then determine what it was and then reached out to me. Really happy with the result
8am brought my 2019 Yukon XL in to service Transmission both differentials and transfer case, oil change tire rotation and multi point inspection Was told it would take 2-3 hours. 11:39 Texted their system to see if car was done-recieved no response 12:18pm called service dept told they are working on it and they will contact me when done 2:23pm called service dept again and was told the guy was working on 2 cars at the same time and he will have mine finished in 30 minutes They would send someone to pick me up at 3pm I live 10 minutes away 3:30 I'm in service dept one other customer was being helped by the rep that was handling my car. The other 2 service reps were at their desks, never bothered to say anything to me for a while or even offer to help me until I finally got eye contact with the rep named Jason. I said I was there to pick up my Yukon and he turned to my rep who was still helping another client. She told him my paperwork was in the basket. He grabbed it and walked me to the counter to pay. He gave no explanation of what was done or breakdown of the charges as is customary when picking up a car. When the clerk told me the amount of almost $1000, I decided I wanted an explanation or understanding from the service dept. So I walked back to service dept but my rep was not at her desk, so I addressed the rep at the next desk, Jason. I asked if there was any reason he did not go over the paperwork with me. He said didn't my rep do that. I said no. I said I was told it would take 2-3 hours and that was 7 1/2 hours ago. the only communication I had was they are working on it and He is working on 2 cars at the same time. Jason replied she will be back shortly. I waited a few minutes and became impatient, so I went back to the cashier's desk and paid the bill. I walked back to the service dept to see if my rep had returned. She had not but Jason had his back to me and was talking to the other rep. He said with an attitude "It's not my problem Don't xxxxing complain to me" Jason then turned around and saw me. I said "I heard that. I am never coming back here again. I am done with Boucher GMC!" and left. It should be noted that Jason has been there several years and my interactions are never pleasant with him. He is annoyed half the time whenever asked questions. In fact about 4 years ago when I had my engine replaced (under warranty) I had a disagreement with Jason. When I picked up the Yukon he was going over the paperwork. The paperwork had stated it was a rebuilt engine. They had my car for many months stating they were trying to locate a new engine which was difficult (covid times) They entire time they always stated new engine. Not once did they mention a rebuilt engine. So when I stated that to him Jason point blank told me a rebuilt engine is a new engine. We argued and he was insistent and arrogant. I may be a woman but I am not ignorant,. Calling a rebuilt engine new is like calling a refurbished appliance new or remodeled home new. It simply isn't true. It is "like new" but it is not new. I cannot believe Jason continues to hold a job in customer service. We will not be returning to any of the Boucher car dealerships. I had continued to give them a chance but I am done. I hope this helps others avoid the aggravation I have experienced
Sales process of my new-to-me GMC was flawless! Nick, Scott, and Cory were nothing less than top notch
My appointment was scheduled quickly when the part for my recall issue was received. Everyone from the greeter when I arrived to my review of what was done was courteous and made sure all my questions were answered.
Oil change was easy to schedule and was able to get in on short notice. Service was fast and car was was a bonus.
I wasn't informed about the diagnostic cost til 3 hours of me sitting there with no updates THEN dudes came in (1 cust 1 sales guy) and changed the channel while I was watching...I clearly didnt matter as the guy mumbled about the view...seriously, cause there was women, racial or???? Just a handmaids tale of a moment. I was trying to get work done on existing vehicle as im ready to trade and buy new...it will NOT be Boucher...im good!
Great dealership, all staff members are superb! Entire experience was terrific. Greg Prince is a true gentleman.!
My sales person Gregory Prince's customer service was great, along with the finance department. Thanks
Not interested No Wonderful nice kind helpful. I shouldn't have to write something if I don't want to
We were treated fairly and appreciated the service provided . We would refer this dealership to anyone who would ask.
