More Than A Repair Shop

Aren't we all looking for the shop that is not only going to fix our car problems, but educate us about our vehicle and teach us how to prevent problems in the future?

Castle Automotive's owner, Ara Derderian, and his staff not only want your business now, they also want to see you happy with their work and coming back for regular check-ups for the life of the vehicle. They have a love affair with cars that starts with diagnosing problems and ends with hearing cars start up and drive off the lot performing the way they did when new.

When you come to Castle Automotive, your car has finally found its home away from home. Castle Automotive feels that the people of Los Angeles have to put up with enough smoke and mirrors when it comes to car repairs so come to Van Nuys for the real thing. Castle's staff is here to diagnose your car's problems and repair them. They want to get you back on the road as quickly as possible.

What Our Customers Have To Say

Zachary G

This is the place you have been looking for. Ara and his mechanics are honest. Period. That's the best news to hear about a repair place. Honesty. Give them a try and I hope you bring your cars to these people from that day forward. Simply a solid honest knowledgeable car repair facility.

Katrina B

I've been taking my car here for years and Ara and Steve are trustworthy and have been beyond helpful. They are thorough with what needs to be done and will discuss in detail what they did and always keep me informed about what care my car needs and when before moving forward with repairs. A+ in my book!

Alysia E

I literally cannot recommend this place enough. Castle has been my go-to place for the last two years. As a woman without any car knowledge I always get nervous taking my car into a mechanic, but Ara is kind, explains what's going on with car in terms I understand and always make sure I know and approve the cost before they do anything.

Tony K.

Castle automotive did all my front and back brakes very quick. Ara, the owner was very very helpful and nice. I didn't feel like I was just getting talked into fixing a bunch of random things. They did a great job on my car and I would definitely come back for any issues with my car. Definitely recommend to anyone around the valley.

M. W.

I've gone to dealers and independent shops for years until a friend recommended this unassuming place in the middle of the Valley's auto repair stretch. Never will I go another place again. Ara is the most honest and respectful mechanic I could have ever hoped for. I have happily recommended Castle to all of my family and friends. There is no better repair shop in LA.

Tammy B

These guys are THE BEST around. Very knowledgeable and reasonably priced. Nobody else works on my family's cars!

Simone L.

I've been going to Castle for years and now my parents, brother, and close friends do too. I once took my car elsewhere in an emergency and ended up making the extra effort to have it towed to Castle anyway for a better price and better service. Steve and Ara are honest, trustworthy, and efficient. I'd recommend them to anyone!

Mark H.
