It is a pretty good diagnosing of the car when you take it in. Good communication when the car is worked on.

by - Verified Customer April 20, 2016

It was good service. I asked them how long they were expecting it to take and they were very proficient in their response. I Have no complaints.

by - Verified Customer April 07, 2016

Their service was quick and reliable. They got the work done really quickly.

by - Verified Customer April 03, 2016

They did a good job. They did what they needed to do.

by - Verified Customer January 26, 2016

These guys are great. I love them. They are honest and quick. They do good work. I like them a lot. It is rare to find these days.

I took in my car and they repaired it.

by - Verified Customer December 07, 2015

I felt they were very thorough and each time they fixed it, one time, the last time, when I picked the car up, whoever the mechanic was, if there were smokers, my car smelled bad cause of smoke, they shouldn't allow the mechanics to smoke while they are working on customer's cars. The car stunk real bad for several days like cigarettes. It is pretty offensive to the customer if you don't smoke. The people are friendly, and on time, and other than that I was pleased with the work.

by - Verified Customer August 17, 2015

Very, very good. They are always friendly, approachable, and knowledgeable. Treated with a lot of respect and the work is good and reasonable.

by February 19, 2015

Most of the stuff got repaired and still are working on some of the original things that needed to be worked on. things I took it in for. One of the things I took it in for didn't get repaired when I took it in. I had to take it in for something else and they were still repairing for the first things I took it in for.

by - Verified Customer February 19, 2015

They did everything I asked them to, and I feel they priced their work fairly.

by - Verified Customer February 04, 2015

I have had a car for repair on the assurance that they could do the job, and afterwards they called and said they did not have time to work on the car. I had to spend more money to have it towed from there to another shop.

by - Verified Customer February 02, 2015

They did a really good job, they said they would be done in a certain time and they were.

by - Verified Customer January 30, 2015

They treated me pretty nice and are real fair on their prices and they did a good job.

by - Verified Customer January 29, 2015

They are very good. The main technician is German and he really knows what he is doing, and all of their work is magnificent.

by - Verified Customer January 28, 2015

They are good, they know exactly what they are doing.

by January 25, 2015

They were pretty good at getting an appointment.

by January 20, 2015

I don't like their attitude. The employees are rude. The only one I like is the owner. I don't like that place at all. The owner is the only one that is polite.

by - Verified Customer January 18, 2015

They told me they were going to do something and they didn't do it. They were very dishonest. They told me I was going to be charged 20 maybe 25. They didn't even know what was the problem. They said they didn't have computer or the right equiptment. They were waisting my time.I took half a day because I was waiting for them to test my car.

by - Verified Customer January 15, 2015

I had some transmission work done. I had two or three things done there and they did a really good job.

by - Verified Customer January 11, 2015

They have a great reputation, it's a busy garage, and they know what they are talking about.

by - Verified Customer December 22, 2014

They put in a new catalytic converter for me, they were very helpful and they answered any questions I had.

by - Verified Customer December 16, 2014

They ordered an engine and put it back together instead of getting the parts.

by November 25, 2014

They are professional. They solve problems that I would have never seen and brought it to my attention. They were concerned about what I wanted, and concerned about the whole vehicle.

by November 19, 2014

They kept me updated with everything they were doing to my truck, any questions I had they answered so that I knew what was going on.

by - Verified Customer November 19, 2014

I think they did a really good job. They sorted out my Mini Cooper. It's hard to find someone who works on Mini Coopers in the Rio Grande.

by October 19, 2014

They give good service. The prices are good. I was very satisfied with everything.

by - Verified Customer October 15, 2014

They did a great job at a reasonable price.

by - Verified Customer October 09, 2014

They did a great job on my truck. It's hard to find people down here that you can trust. I was really pleased with their work. I had a whole list for them to do. They talked to me before they did anything.

by - Verified Customer October 09, 2014

It was excellent and the price was great. The people were great,they did a good job. They didn't rip me off like others. What they did to my car lasted. A lot of mechanics in the area rip you off, they didn't rip me off. They were courteous and good people. They did the work really fast, I highly recommend them.

by - Verified Customer October 06, 2014

They are very knowledgeable. They are very reasonably priced. They are very accurate in their work.

Try this, put the key in the ignition while trying to turn the key move the steering wheel back in forth (right to left) as much as you can. Sometimes the steering wheel lock will hang up. Seems to be a common problem on older mb vehicles. The door lock problem will be the plastic tab lock on the backside of the lock tumbler. It will require removal of door panel, outside door handle and striker in some cases.

you will need to have a scanner to turn the light off as the newer vehicles have a computer with a keep alive memory. this means that when the battery is disconnected it will not clear codes on the DME control module. Most shops will perform the scan test for a nominal fee

these cars have two batteries. the main vehicle battery, and a auxiliary battery located on the right side of the vehicle under the hood. I believe the washer tank will have to be removed to gain access to it. It will cause the vehicle to go into what is called energy saver mode (ac will stop working) and the red battery light will come on

have you checked the fluid? is it leaking anywhere. when is the last time the trans was serviced. was it slipping the last time you drove it? The questions will go on and on. Start with the basics. also check to see if the reverse lights come on when shifted into reverse, Make sure to set the brake and do not start the car to check just turn the key on. if they light up that would mean the linkage from the shifter is going to the transmission shift lever, if not then check to see if the linkage bar has come unhooked from the shifter to the transmission. the bushings and clips wear out and cause problems like this
