Not often do you have a great experience buying a vehicle, for most of us it’s hard to know if you can trust a dealership and the sales department. Firas and Ahmad are top notch. No hassles, they give you all the information you need to make the right decision. Once all the paperwork is done Firas took the time to go over all the features and infotainment system in depth for me,and even hooked up my phone for me. Came to the dealership needing a new vehicle left with a new truck and new friends. 5 stars for everyone at imperial.
This truck has a jerk when changing gears sometimes.

Doug White was amazing He sold me my last car and was so
Doug White was amazing He sold me my last car and was so helpful again. The windshield in my new 2019 had a chip which I was told would be taking care of with a new windshield before I picked up the car. That didn’t happen. They sealed it and it was front and center to my view. I’m short. It rained most of last weekend and I hardly drove it. Then the sun came out. My friends all said what’s that in your windshield. Unacceptable. Then I was trying to make a time to bring it in for the replacement and the guy said we could rent you a car for $42 a day. Even though that didn’t happen why would I pay for a rental when you inconvenienced me by not doing the windshield before pick up. My friends were saying shocking. Tasca is a reputable business. Ok done venting. None of this is Doug Whites fault. Thank you

Only place that helped us
We had a poor credit rating, and Advanced Auto Sales was the only place who gave us hope. Everyone is very nice and knowledgeable salesman and finance. When we went to pick up our car, everyone there was happy for us. I highly recommend them.

Excellent, no-hassle service. Both the salesperson (Victor) and finance manager (April) were low-pressure. The focus was on getting us the right car for our needs in our budget. I usually hate car shopping, but Victor and the Tasca team were a pleasure to work with.

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 .
