Awesome experience.
Awesome experience. John Bruno was my safe professional and did an awesome job! Traded my daughter’s car for the new car so she could have my older GMC. I recommend Tasca Buick/GMC highly!!
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Purchasing a New Bronco
Lorenzo, Mark, and Sean went over and above helping me with the order of a new Bronco. They were all very knowledgeable. I had a great experience. Definitely recommend purchasing a vehicle from Veteran’s Ford!!
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

I recently bought a Toyota Camry Hybrid from Sun Toyota.
I recently bought a Toyota Camry Hybrid from Sun Toyota. My experience was not short of wonderful. Chris Robinson helped me find my dream car and was more than fair with the trade in price for the Camry that I was trading in. Everyone from Chris to the guys in finance and service were so nice and professional. I have been buying cars from Sun Toyota for almost 15 years and have always received excellent treatment. This time was no different, but I have to acknowledge Chris Robinson for making everything so easy and smooth. The whole process took less than two hours. I drove off the lot with my new Camry Hybrid, and all my Bluetooth devices set up for me (thanks to Chris). If you are thinking of buying a Toyota new or used, I highly recommend Chris Robinson of Sun Toyota.
