Seamless and positive experience!
My salesperson was Malcom. Very responsive and knowledgeable. Every single person at this dealership was amazing to work with, even the ones who weren’t working on my sale specifically. The finance person, the manager, other salespeople, pretty much every employee I came into contact with was great to me. My biggest fear was being lowballed on my trade in. That DIDN’T happen!!!! I was offered a reasonable value that I didn’t have to try and negotiate. What I expected to get on trade in value was within less than $1000 difference. From phone conversations to in person experiences, this dealer proved to be top notch! Would absolutely work with the staff at Brandon Ford again!!

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.

I just purchase a car from these guys.
I just purchase a car from these guys. From the moment I called, they had the car pulled up front. To the test drive with Jose'. Very easy person to talk to. To the credit manager, office manager, to the owner. They were all easy to work with. I have never had a more comfortable experience puchasing a car. Just bring your info with you, they even transfered a tag right then in there. I was looking at a few other dealers before going here. I'm sorry I waisted my time with the others. I would tell everyone to go here. Best experience ever!

just now New Excellent experience from initial visit to picking up my GM certified truck! Note we aren’t local to the area but live 97 miles south of the dealership. It was worth the trip 👍 I really appreciate how the team at Tasca listens to you rather than try to bulldoze you thru a canned process like most dealers. They were flexible and responsive to how I wanted to evaluate the vehicle I was interested in buying and my timeline. Have to give shout outs to so many individuals. Cassandra promptly responding to my internet inquiry, Dillon the sales manager setting up my first visit, Nolan my sales professional meeting me for the test drive then taking care of everything up to final delivery and Melvin the finance manager who made sure the money part went smoothly. I know there were others behind the scenes who am thankful for as well. Definitely recommend! Would definitely buy from them again. Worth the drive & time!!
