The guys at C&M always provide a high quality of service for a reasonable price - and they stand behind their work.

by - Verified Customer August 25, 2016

I had an honest assessment of what was wrong with my car.
I anticipate taking my car back in a few weeks for the major repair.

by August 22, 2016

Quick clean repair work

by - Verified Customer August 19, 2016

C & M was very informative and helpful regarding the issue that I was having. They worked in a timely manner and were very professional.

by - Verified Customer August 10, 2016

There's nothing like driving a vintage auto, and being able to do so with confidence. Because of C&M Automotive, I can have the confidence that my car will remain in tip-top shape. If there is a strange noise, an odd rattle, or something just doesn't feel right, the folks at C&M Automotive know how to find it...and fix it. I have recommended them to everyone I know who needs work done on their ride. That's how I heard about them after moving to Simi Valley. Word of mouth is the purest advertisement.

I used to trust C&M, enough that I spent over $4000 on my last repair, but when the car still didn't pass smog and they insisted they had to charge me $100 to get the O2 sensor to work despite all the money I had already spent, I'm done. I thought they used to be honest, but it turns out whatever happened over the last eight years, now they're just greedy.

by - Verified Customer August 04, 2016

My last experience at C&M went as well as could be expected for a basic service pertaining to an oil change and engine check-up, followed by an update for future routine servicing. All is well that ends well.

by - Verified Customer August 03, 2016

A little expensive but they did a good job!

by - Verified Customer July 23, 2016

Overall I have only one complaint with the shop -- they always switch my headlight settings from auto (always on when the engine is on) to another setting which has the headlights on but no dashboard illumination. Not good when you are in the dark and of course not noticeable in the daytime.

by - Verified Customer July 22, 2016

Great guys, always seems to cost a fair bit, but in the end they get the work done right as far as I can tell.

The personnel were professional and friendly. They performed the repairs necessary and in a timely manner.

by - Verified Customer July 12, 2016

the problem I took the vehicle in for was not fixed. Many expensive repairs, and nothing done that resolved the issue. The exact same problem persisted as soon as I got it back - they appeared to not be able to find the issue and resorted to "trial & error" methods to fix it. Very expensive for me to have to go through that. Not at all satisfied.

by - Verified Customer July 05, 2016

Always informative and they get the work done in a timely manner

by June 13, 2016

The repairs are good so far so I am happy about that. Job took longer than I expected it would, but no complaints. Thank You

They are Honest and professional

by - Verified Customer May 06, 2016

The team was fast and the repair was solid. I really appreciated the breakdown of what was wrong. They separated it into, must fix, fix this soon, keep an eye on this. That helps especially with an older car.

by - Verified Customer May 03, 2016

The service was very good as well as the hospitality. I think the pricing is a little high especially on basic service procedures like oil changes and fluid additions.

You guys are awesome!

by - Verified Customer February 05, 2016

They have very good customer service, and great communication. They will always call and inform me of their progress, and they are very transparent about what the potential cost might be. They'll give you options about what they could do, and they're careful to not do any work unless you approve it first.

by - Verified Customer February 04, 2016

They provided good service, and the work was done correctly. Everything went smoothly, and I've taken my vehicle to them before with the same results.

by February 01, 2016

They have good customer service and they did their work fairly.

by - Verified Customer January 30, 2016

I believe they are honest, I believe they do an excellent job, and they are able to find out what's wrong and fix it. They also provide you with a loaner car if it takes a while. I can't think of another place that I have gone that I could say that about them.

I think they are pretty honest dealers, I trust their service.

I've been going to them for a long time, and I find them very honest. I trust that they won't overcharge or take advantage of me just because I'm a woman.

by - Verified Customer January 29, 2016

They are very honest. They don't try to sell you things that you don't need.

by - Verified Customer January 27, 2016

They helped me out a lot, and they answered and explained every question I had very well.

I know the guys who work there very well, I've been going there for quite a while. They always explain what they are going to do, and they will tell me what needs, how soon it needs it, and what can wait.

Fair pricing, quality work!

by May 30, 2014

Too much of a push to upsell on belt and hose replacements. They briefly (if at all) discussed their actual wear-and-tear condition and went to the "Manufacturer recommends this need to be replaced after X" guidelines. However, the shop is clean, staff is respectful, and nothing was stolen or damaged in my car, so they definitely conduct themselves in a professional way.

Last service was a diagnostic, they failed to diagnose my problem.
