Sales person was Very pleasing, knowledgeable, and
Sales person was Very pleasing, knowledgeable, and helpful Not high pressured Made to feel very comfortable Since we were not familiar with many of the features Darnell was very good to let us know we could call him anytime to ask a question
Most money I've ever saved on MPG
Car is super comfortable, spacious interior with a big body size for a 4 cylinder car. Definitely is great on gas, I drive lot of highway miles and get upwards of 30 miles per gallon which was great in comparison to some of my older vehicles I had. Would definitely recommend this car for someone who travels a lot on the highway to get to school or work.

A very special Thank You to both Chad Sigsworth (Sales
A very special Thank You to both Chad Sigsworth (Sales Associate) and Patrick Amann (Service Associate) who both assisted in the replacement of my engine. Both gentlemen were dedicated from the begining to the end of this replacement. They both stayed right on top of things and kept me well informed until the job was completed. I will always purchase any future vehicles through Dave Sinclair due to their honesty, dedication, and treatment of their customers. They have one of the best staff I ever had the pleasure of working with. Keep up the great work. Sandra Hearn
I have a 2005 Grand Marquis LS, and this care is awesome!
I have a 2005 Grand Marquis LS, and this care is awesome! I did modify it slightly with a K&N cold air induction and custom made dual stainless steel exhaust. The car is so great for cruising because it is like sitting in your living room on the couch.

I was working with this dealership back in September 2024
I was working with this dealership back in September 2024 and was looking for a traverse In within two days of asking, John Cushman found the traverse with everything in the exact color I wanted. I looked all over Columbus for it and couldn’t find it. He bent over backwards to help me now we are going to look for a 2025 new truck And I’m sure we will have him look around and find the truck that we want since he was so helpful with finding us our traverse. Can’t wait till spring, so I can come back there again and check out your line of trucks. Even after I got home, I called him several times and asked questions where to find this or that and he answered me promptly that same day. See John in the spring 😍
Great price on very low mileage car
So far car is great. AWD will be nice in the snow. It has plenty of interer room and adaquate power. Color is nice and tires are new.
