Crappy dealership

They had me put a downpayment and get financed then sold the truck to some one else , told me they would make it right buy getting me the same truck for the same price after waiting 2 and a half weeks for the truck to come I find out the truck has 3,000 more miles and they want to charge me more money. I dont know how that is making anything right customer service is garbage . They should really be ashamed of the way they treated me

Dealer response

Jason please give me a call 906-226-3592. Thank you Nikki Remilong


bought a new 2020 1500 Sierra truck

Great experience with Sales person Kevin and manager Nikki. It couldn’t have gone any smoother. I was more than satisfied with the deal we made


Top Shelf

I have a fleet that is maintained at Marthaler. The service dept is top shelf. The sales staff work with me no matter what my changing requirement dictate. Every visit there is positive and the whole staff help meet my needs. A shining example of how a dealership should be run.

Car shopping

My husband and I went in with our budget and they honored our budget and worked with us. No pressure for extra things above our budget and treated us the same as someone buying brand new vehicle. Nice to see the owner of a big car dealership taking interest in his customers and dealerships.

Surprising visit!

I stopped in the showroom at Marthaler in Marquette to “maybe” look at a car I had seen on the website. After 2 days of looking at 3 different cars I bought a 2019 Chev Equinox. David Heard was the salesman, he was patient and very polite. Answered all my grueling questions, sometimes twice, and took care of everything for me from getting a loan, to switching my plates and insurance. I am very happy. Thank you David.

Dealer response

I am happy to hear your time spent with David was pleasant. Congratulations on your new 2019 Chevrolet Equinox! If you have any questions or need any further assistance, please come back to visit us. We look forward to seeing you in the future. Sincerely, Hayes Piker, GM at Marthaler Marquette

Purchase of 2019 GMC Acadia

I just purchased a 2019 GMC Acadia yesterday from Marthaler and it was a seamless process. From my salesperson, Charlie Crabb, to the business manager, Cassie Herman, they went above and beyond for me. FIVE STARS!! I love my new car and I will go back to Marthaler for my next vehicle purchase!!
