Optimum quality service
Always courteous, professional and informative. And they do not try to sell you unnecessary services/products. I feel I can trust them having used their services over 4 years.

Got my certified Car Bravo Chevy Tahoe from Peter
Got my certified Car Bravo Chevy Tahoe from Peter Franklin. There was no pressure. I got a great price that cars.com confirmed ahead of time for me. Peter made sure it was the right car for me and the experience could not have been more pleasant. If you want a no pressure experience buying a car go see Peter Franklin at Herb Connolly Chevrolet.

In search of a low mileage, newer vehicle to replace our
In search of a low mileage, newer vehicle to replace our 8 year old pickup with a well-equipped replacement, we found an ultra-low mileage, full-featured high-efficiency pickup at Imperial. Firas Ektilah was friendly, professional and well-informed to answer our questions and provide a test drive and all of the vehicle information I needed to determine the vehicle and options are an exceptional value and We negotiated a vehicle price that was highly competitive and provided top value for our trade, which was previously purchased from Firas. We then completed the purchase and sale with Ohmar, who took the time to review the extended warrantee on our trade and provided as much of an extended warrantee on our purchase that was in our budget. The vehicle was then professionally cleaned inside-out and filled with fuel. This proved to be the easiest, most valued vehicle purchase experience we've ever experienced! We look forward to returning to Imperial Chevrolet to have the vehicle serviced, as they have provided exceptional service to all of our vehicles, including one we didn't originally purchase there. We've also been impressed with the competitive service rates and timely discounts Imperial Chevrolet has provided when service is due on any one of our vehicles. When it comes time to replace a vehicle, Imperial is the first and likely last stop we'll make!

If it wasn’t for the Service Manager Dominic and Customer
If it wasn’t for the Service Manager Dominic and Customer service rep Matthew who works for Dominic, the vehicle would have been sold months ago! They both went out of the box to get all issues fixed . I can’t say enough about these two and have repeatedly tried contacting the District Manager for Tasca GMC in trying to let him know that they’ve secured our loyalty. We’ve purchased more than 7 vehicles from Tasca and didn’t want to take our business elsewhere. TY Tasca for having such valuable employees. Nicole Saunders Owner of 2024 GMC Sierra Denali .

Midway Automotive
They were excellent. They got me right to the car I was looking for and They did not attempt to add any illegitimate fees to increase the price. They got the car ready for me so I could pick it up the next day ready to go. The experience of getting a car from this place went as well as it could have gone. I highly recommend them. The person who helped me was Frank Santino and he was easy to work with.
