Extremely fast and reasonable to work out a deal with. Michael was amazing - helpful, knowledgeable, plus none of the stuff you worry about encountering at a car dealership.

Always a pleasure to work with. We've leased or purchased several vehicles from Markley.

DealerRater Mar 30, 2026

We have purchased and leased several vehicles from Markley and have always been satisfied with fair prices and fair trade in values. Michael Shelleman is always very helpful and knowledgeable in finding the vehicle we want and educating us with all the options and technology in the vehicle. We just wouldn’t shop for a vehicle anywhere else other than Markley. Thank you to Michael and Markley Motors. We love our new GMC Sierra.

DealerRater Mar 3, 2026

Tom Medina is knowledgeable of the GMC Sierra pickups and is great to work with. Didn't pressure the sale and helped with my decisions. I would recommend him to anyone.

DealerRater Feb 10, 2026

Michael was very well educated with the features of our vehicle. What I didn't care for was during the selling, Michael brought out all of the good points but at the end it was stressed to buy warranty protection for all of the bad reasons. I figured if the vehicle was that bad I may not buy.

DealerRater Feb 7, 2026

Michael was very informative and knowledgeable. He was easy to work with and made the overall experience great.

DealerRater Jan 28, 2026
