Owner - brought car in for routine service
Maintained their always high standards in the midst of the coronavirus challenges. Excellent service for the car. Easy scheduling and quick turnaround while fully respecting the additional risks that the virus posed in the pick up and delivery of the car. They will always get my business.
Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.
