I always receive excellent service from Colonial.
I always receive excellent service from Colonial. Last time they stressed how important fuel injector cleaner is for my vehicle, however this time they didn't mention the cleaner and when I brought it up they said they would take care of that next time. How important is it really? Just left me wondering and thought I would mention it.
Nicest, best performing truck I've ever owned

Great Day @ CarMax!
A few weeks ago my son and I bought a 2016 Hyundai Sonata at CarMax of Southlake on Mt. Zion Road in Stockbridge GA. Our sales agent was an older gentleman named Jim Lowe. What a nice guy. Low key. Not pushy. So very patient. He was very knowledgeable about the various cars my son wanted to look at and understood what features he needed on the car. He never rushed us to get on to the next customer and was always willing to answer all our questions. (And he even knew the answers and didn’t have to go ask someone.) These are attributes that you don’t always find with used car salesmen. But Jim was different. CarMax is different. Such a large selection of cars that we found and with low or mid or high mileage. The financial process was painless as well. We went outside to go get his car and found it all washed and cleaned inside. It even had a full tank of gas and a HUGE yellow bow across the hood. Such a nice way to send off the customer. I highly recommend CarMax for your next car buying experience. Also, ask for Jim.
