Transparent and excellent service
While I haven't bought from them, yet, simply inquiring about a car was such a smooth process. They responded to my inquiry within the hour and were clear and honest about where the truck I was looking at was. While the truck I was looking for was sold, they asked for my preferences (offering to pull inventory from 5 lots) while promising to keep me in the loop regarding trade ins or auction cars brought in. Super friendly and excellent service
This truck has a jerk when changing gears sometimes.

I went to Shea Buick GMC because their inventory of
I went to Shea Buick GMC because their inventory of preowned vehicles had many selections of the models that met my needs as far as mileage, year of manufacture and price. I actually bought the vehicle I had been the most interested in since March. I made an appointment, the salesman met me at the door and had the vehicle I was interested in with the air running ready for a test drive. It was perfect! We added a tonneau to the package, agreed on a price for the trade-in and the purchase price for the truck I bought. We arranged for the insurance, the installation of the tonneau and for a pick up time at my convenience. All was done in a matter of 2 hours! Everyone I worked with was kind, focused and professional... the efficiency of the transaction speaks volumes to the dedication of Sheas' staff!

Thanks to Tony Hauck for an excellent experience!
Tony Hauck was absolutely the best car salesman I’ve had the pleasure of working with. Instead of giving the typical car salesman scripted approach, Tony listened and made the whole process very quick, easy, and comfortable. Although we have to pass multiple other GMC dealers on the way to Frankenmuth, we will gladly make the trip again due to Tony’s excellent support and service.
