After driving by my local Westborough MA, GMC dealership several times I decided to inquire about the new GMC Hummer 3X SUV parked out front. I tried to call the dealership as I was on my way to Boston seve several times I decided to inquire about the new GMC Hummer 3X SUV parked out front. I tried to call the dealership as I was on my way to Boston several times with no return call. Finally, I sent an e-mail through their website again with no return call or e-mail. Finally, I spoke to a person and inquired about test driving this vehicle. This particular woman advised me that I had to qualify to purchase, before they would allow me to test drive the vehicle. After a few minutes on the phone, I felt this person to be……. well, let’s just leave it at, unprofessional…. I decided to contact Diamond in Auburn MA as I have had experience with them in the past. I spoke to Mike Monfreda who said that he had the exact vehicle I was looking for…. to come anytime to take a test drive. When I arrived at the dealership the brand new 2024 Hummer was out front with the air conditioning on. Sales Rep Hector Villar accompanied me on the ride and within one hour I decided to purchase the vehicle. Mr. Monfreda helped me transfer my insurance and license plates I was on my way that afternoon. However, not before Hector spent approximately 1 hour with me showing me all how to operate the vehicles extensive operating system. Prior to leaving the dealership Jon Massad came down shook my hand and thanked me for utilizing their dealership for the purchase of this vehicle. I can't say enough about the stellar treatment from these three gentlemen I received. By the way they also gave me a great deal on my trade-in… Paul M Westborough MA More
