Blasius GMC review
The salesman was great.
The salesman was great. No pressure and willing to negotiate. The finance guy was even better. Overall great experience buying a car.
2024 GMC Sierra 2500 Denali review
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Blasius of Middletown review
Very easy to work with
Edwin was great to work with from the beginning. He reached out shortly after I inquired about the car and scheduled a time the next day to take a test drive. They were able to complete the purchase that day so I could take the car home. Overall, both Edwin and their Finance department were easy to work with.

Sound Auto Wholesalers review
This was the best experience I’ve ever had in all my
This was the best experience I’ve ever had in all my years of purchasing cars. They understood my situation, worked hard to accommodate my needs and most importantly they knew my urgency. They made it happen and did all the leg work so I did not have to. I walked out of there with my new used vehicle, insurance and registration. At the end of the day the hardest thing I did was wait while the made it happen. I got into my dream car for the family. May God continue to bless this business and I am worry free with a lifetime warranty on the engine. Thank you Sound Auto Wholesalers

Blasius of Middletown review
2019 Jeep Compass purchase
Edwin Ocasio was very professional and listened carefully to what I was looking to buy in a vehicle as well as my price range. As I test drove he answered all my questions in detail. After purchasing my Jeep Compass I noticed one issue that needed to be fixed. I brought vehicle in the next day & it was taken care of. Thank you Edwin for all your help. I I am very happy with my purchase.
2022 GMC Sierra 2500 Denali review
Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.
