I own a 2000 Porsche Boxster with 61,000 miles, so I came for the 60,000 mile service. I had an extremely positive experience at Zentrum. Three words come to mind with regard to Zentrum Motors…CUSTOMER SERVICE, HONESTY and WOKMANSHIP. Joe greeted me, sat me down and assessed my needs. I told him that I was concerned about the rib belt. I had purchased the car recently and was unsure if the rib belt had been changed. As it turned out the rib belt was good and it did not need changing They could have told me different and I would not known the difference. They replaced the spark plug coils as they were cracked. And repaired/replaced leaking sparkplug tubes among other things. The car is now running soooo good. And a gain of 3 miles per gallon is the tangible proof. From here on out only Zentrum will touch my Porsche. Robert Reed

One of the last honest auto services shops around. The don't overcharge or find things you don't need. Fast in and out repairs. I take my bimmer there for engine service and windshield repairs. Have even taken my motorcycle fiberglass fairing there for repair sanding , and sprayed with primer. My friends take their cars here for collision repairs and painting .I'm restoring a 1968 car so taking our car to this shop for painting and rusty floor pan replacement. Bruce is the best for detailing. Talk to Nam or Tony . The best team around.

OMG SO GLAD WE FOUND THIS PLACE!! My Porsche needed the "dreaded" IMS bearing and I didn't know where to take it that wouldn't "bend me over" and this place was GREAT!! They were priced right and provided us with SUPERIOR service that made us comfortable with leaving our car while it was being repaired. The owner/manager explained EVERYTHING that my 911 needed and would need in the near future and had an exceptional knowledge and working history with 911 Porsche's. I also noticed while there that they work on BMW and Mercedes so I will also be bringing my other cars here as well! My Porsche RUNS GREAT and we can't thank Joe, Annie and their staff enough for making this such an easy,fast and educated experience!! We can't say ENOUGH good things about this shop! Nice to find such an honest and personable place to take our European cars!

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

Great shop and crew! Very honest. Best auto shop that care about your needs and concerns. My Honda runs great!

This is the place I will return again and again! I am very impressed on how they handle the entire process of my car trouble. I was changing out my drive belt and ac belt, not only their price was more than reasonable but their work was spot on! I was able to get in and out fast. Also ask for an oil change while I’m there and it was not a long wait at all! They were upfront about the cost and give me a detailed break down. They also warned me about taxes and fees that may apply later at check out. No hidden cost that will surprise you later. Overall, I am very pleased with my service and I will return with both my cars for any service needs. Thank you RC auto for taking care of my car! Ben Chang

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

Very nice experience

I've been bringing my car here since I bought her and have received excellent service every visit. German is an exceptional business owner and very pleasant to work with. He is great at explaining things to someone who is not car savvy at all! Danisela Mancia
