Vance Auto Group Guthrie review

Tim internet buyer

In the days of corona virus John Vance motors was offering internet buying. The offer by Mr. Vance on video seemed sincere. Since it was sight unseen I expected the sales force to be my eyes and ears on site and be and do more than if I were there to check things myself. I asked several questions about various things, got affirmative answers and was assured twice that "they check everything". When car was delivered (400 miles) there were many things that were wrong (they did not check everything), without going into detail of all the problems I notified the sales people by email, no response. I notified John Vance, the owner, and can't say enough good about John. He took care of things immediately and as much as possible for me being distant, said that is not the way they do business. I believe him, and I feel confident that the next internet sale will be treated with integrity and double check "everything" thoroughly. If only reviewing John it would be 5 star.

Confidence Chevrolet Buick GMC review

Ladies shop here!

Ladies, ask for Jimmy Briseno! For the FIRST TIME we found a salesman who answered MY questions and catered to ME when buying a car! The minute my husband told him it would be my car Jimmy went above and beyond to show me multiple options, all while really listening to what I liked/disliked about each car I test drove. He was patient without being pushy and didn't treat me like I was silly just because I'm female--absolutely recommend!

After taking my 23 GMC Sierra 1500 Denali for a diagnostic service at the dealership where it was purchased I left there with no resolve; so I took it to Bob Howard GMC and I?m glad I did. Mark in the service dept. took a genuine interest in diagnosing my trucks issue and ultimately got it running like brand new. He gave some good information about the use of Top Tier gasoline and even recommended where I could buy it for a reasonable price which was great! I?m taking my truck to Bob Howard GMC from now on! Thanks Mark!

Vance Auto Group Guthrie review

A pleasant experience.

Back in December 2020 we sent out inquiries to twelve Jeep dealers within 70 miles of Stillwater (our home). Only six bothered to reply. Of those six, your salesperson, Jennifer Medina, was by far the most enthusiastic and helpful. She sent us two separate videos introducing herself and wanting to take care of our Jeep purchase. Solely because of Jennifer, we recently purchased a new Jeep Sahara from John Vance Auto Group. Jennifer facilitated that purchase. We found the whole process to be quite satisfactory. The Jeep arrived just as we had ordered it, and was transferred to us for the price agreed upon. It appears to be functioning according to spec, and we are quite satisfied with it. We don't normally take the trouble to write a review, but what is really prompting us to do so now is the service provided to us by Jennifer. She was polite, friendly, and attentive on every occasion we dealt with her. When we had questions, she answered them directly and honestly. If she didn't know the answer, she stayed with it until she got one for us. When we took delivery on the vehicle, she suggested a time when she could spend some time with us going over all the things that have changed since our old Jeep. She didn't rush us--let us get the feel of it and ask questions--showed us all the fancy electronic and internet stuff and got answers to questions she wasn't sure of. She is still following up on some of those questions 2 weeks later--bless her. You couldn't have a better representative. Treat her well. She's a keeper.
