Sigma Auto Repair - Huntington Beach (CA)

5 /5 Myra Adawy: Jimmy, the owner of the shop is absolutely spectacular. I have been going to the shop for at least 10 years and have always received honest service. He recently helped me rebuild an entire EJ25 motor in my baja turbo for me when many shops denied me and told me the project could not be completed. I have never ever left Jimmy’s shop disappointed, the labor and quality of service is unmatched.

5 /5 John Erhardt: I use Sigma Auto for repairs on all my familys vehicles. Jim always goes above and beyond to get the job done with honest and quality work. I cannot recommend Sigma Auto enough, Jim is a great communicator who provides various options and makes you feel confident the right work is being done based on your needs. Its hard to find honest, affordable, and quality auto work, Im glad I found Jim many years ago.

5 /5 Matt Poulsen: The best IRF auto repair shop around. I’ve been taking my late model Santa Fe to him for years. Jim is amazing. Always tries to find the least expensive option for parts. Thinks outside of the box for options (Toyota parts for a Hyundai). He will tell you what you have to do and what can wait (but will need to be fixed at some point). Quick turnaround and super friendly. Trust Jim for honest auto repair. 1/25/2025 update: After 8+ years of taking my car (and now my wifes Audi) to Jim, I still cannot believe how friendly, fast, and trustworthy he is. The Audi had squealing (not squeaking) brakes. It took a few tries, but Jim found a fix (at a reasonable price). Thank you Jim and team at Sigma!
