During my search for a new Chevy (I had the GM card with
During my search for a new Chevy (I had the GM card with $8000 off a new vehicle) I found that certain dealerships were friendlier and more helpful than others. I was pleased with the interaction of sales and service at Middletown Chevrolet (Key) especially after being cut down by another salesman at another Chevy Dealership - will NEVER go back there ever. Mike in Sales, Devin/Josh in service are definitely great reps of the company. Both the purchase of my 2025 2RS Trax and first service went very well. It was a quality experience of which I am very happy!
In about 15 vehicle I had, this the best one
This truck just need nothing, comfort, strong, and beautiful, it's great for work, and for personal use, my next car will be the same but new

Bought A 2015 Mini Cooper from John at Lee Auto Group and he went over and above to take care of me He noticed a small noise and replaced the accessory belt. there was also a problem with charging and had it repaired by the qualified and professional mechanics by staying late and in no time had it repaired.
