It Will be Strengthened!
My husband and I have owned Volvos exclusively for the last 35 years. We've been dealing with the Glen Cove dealership in the past 4 1/2 years and found the service to be excellent. It appears that post-COVID there has been a great deal to be desired. That being said the new manager, Vito, has been informative, patient and most willing to answer my questions and resolve the challenges that this dealership has faced. I am confident that he will be the person to bring back the dealership to its place of excellence.
Loving my X3
I am new to BMW and so far I am loving it, especially the way it handles the road and the overall comfort of the car

A lot of luxury for a SUV. Great safety features.
Surprised with the number of safety features on a 2018 model. Also, the ride was very comfortable and quiet. Has a great sound system and fair amount of technology. Much better than the 2016 BMW 328i that I traded in.
