They didn’t give me a hard time at all. Made sure I able to get the car and didn’t get mad or hassle with me when I told them I needed a couple of days to think about it. I definitely recommend South Auto Plaza if you are going to buy a car from Saint Louis. Shout out to Larry and jason for making this possible.

Honestly this place saved me. I really needed a car but i was worried id have to get something cheap that may break down immediately because of my credit! Every one i worked with was so nice and patient. They worked with me and I never felt pressured! 10/10 experience. Hands down.
