Do not go here! The Tech and the Boss were very rude to say the least. They charged my twice for a job they screwed up the first time. Then after three hours of telling them I wouldn't pay them again to fix their mistake, I was PYSICALLY and verbally ATTACKED by the tech. I don't care how much you disagree with someone, it is not okay to PULL YOUR COSTUMER OUT OF A MOVING VEHICLE!

007 mb e350 I have been to these guys two times and both times they handled my car and service with amazing care and detail. First time was for a service check up and their price was unbeatable by anyone within a 10 to 20 miles radius. Second time my car would not start when it was cold in the morning. So I took it to them and after having a diagnostic, turned out my crankshaft sensor was no good. They fixed and teat everything and so far the car runs amazing. Will check back within a week to see if any more problems shows up. Thanks autowerk eurpean definitely my go to guys!

Brian very patiently and expertly diagnosed the reason for my engine suddenly shutting down for apparently no reason.

I have been taking my automobiles to Cactus Care for over 15 years. The one thing that I most like and appreciate is the honesty of the owner Jonathan and his technicians. They always tell you exact ally what is wrong with your automobile, and you can believe that is the truth. They stand behind their work. They are respectful, attentive and courteous. You get in and get out no long waits. Excellent mechanics. Great Great Mechanics
