Testimonials

Charles Coulter Client

My truck broke down on i45 broke my wheel bearing, rotor, brake caliper, break pads, lower control arm, knuckle. Had it towed to big John and he was able to have it all fixed in a day even with the holiday (July 4th) I was back up and running by Sunday morning. Was a huge blessing and so thankful he was able to get my truck going again in such a quick turnaround.

Sabrina Ibrahim Client

I was broken down on the side of I-10 with limited funds. I was able to call a friend that referred me to Big John and Son's. He saved me. He was able to not only fix my car but he saved me money for towing he fixed my car that would not start or move on the side of the road a job that would have cost me at least 1,000 dollars was 600. Thank you for your service Big John And Son's 💖💖🙏

Christina Wesson Client

This man was a life saver! We had called another mechanic (called the first one listed first) who cancelled on us last minute and after reading more reviews I am so glad for that and so glad I was able to get a hold of John and his son to come fix my husbands car! Fixed within hours of them coming out. Very professional, very clean (changed the oil in our driveway and not one drip on the driveway), quick to respond and quick and realistic with time frames and great prices! I would highly recommend them and we will be using them again! Thank you so much John! 🙏1

Nicholas Castillo Client
