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!

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
