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!
S8 Incredible Sport Sedan
Love the power ride quiet and comfort…it drives itself in traffic jams and is like a rocket on the highway. Interior comfort with massage seats and fit and finish was incredible.
