First experience working with Big Star Chrysler we’ve always gone through Big Star Honda. From the moment we entered it was like we found our second home dealership wise! Manny was our salesman and went above and beyond to take care of us. Though it was a used car Manny made sure this vehicle was worked on and like brand new before we drove off with our Sequoia. Big thank you to Manny! I wouldn’t trust anyone else!

I cannot recommend this location enough after the excellent service and very good experience I had with my first time financing a vehicle. Cesar Rodriguez and Raul Silva both worked with me to find a vehicle that suited my needs within my price range. These gentleman were extremely patient and professional when handling the sale. I would also like to thank Mark and Brandon in financial services. They both persisted through technical difficulties in order to deliver excellent customer service all the way to the end. I would absolutely recommend this location if you’re in the market for a used vehicle and I will be returning in the future!
