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 never thought I would be able to recover the $37,000 in
I never thought I would be able to recover the $37,000 in Bitcoin that I had lost online, but CYBER SECURE made it possible. After being deceived by a fraudulent investment scheme, I felt devastated and powerless. Nevertheless, due to their expertise and determination, they successfully located and recovered my lost funds. Their professionalism and support throughout the process were invaluable. Thanks to their efforts, I have not only restored my financial stability but also regained my confidence in online transactions. I highly recommend their services to anyone seeking to recover lost cryptocurrency. CYBERSECURE202(at)GmA1L(dot)COM
best in class
My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

They honored their advertised price.
They honored their advertised price. Danny A. Was very professional and respectful. I purchased a Jeep from him. Most dealerships advertise one price, but won’t honor it when you show up. Very pleased.

Top Notch Experience!
Good day/evening to all you readers. I rarely, if ever, write reviews. I am making an exception for J.J. and Car Stars, simply because of the experience. My wife and I needed a vehicle in a bad way, and were a bit dubious, due to past experiences with the dreaded "sales experience", and getting snookered. HAving set the stage, I was astounded at the lengths that JJ went to ensure that we had the best possible deal, and also explained EVERY aspect in clear and concise terms. Not once was he pushy, or arrogant, or disinterested. Buying a car on a note is not something I do frequently, so I probably will not do it again for many years, BUT if I am in the market, I will make the trek to Car Stars, and give them my money and time. Thank you JJ, and may your business continue to flourish. Michael and Erin Garner- Conroe, TX.
