I have been going to Glenn for a least a decade + to service and repair my 2008 Toyota and a diesel 2016 Chevy truck. I found him by looking for a AAA approved mechanic. (He still is an approved mechanic by the way.). They both run great....and he only does what is necessary. For example, I just took my truck in for 90,000 service. It called for a radiator flush. Glenn said it wasn't necessary as it was done a year ago. Find a dealer or other mechanic that does that! I've never had to take a car back, which is a testament unto itself, but I do know Glenn would make it right if necessary. I've seen classic cars and late model cars. He does it all. I also had a '71 Volkswagon Transporter which he worked on for me as well. Glenn is in his early 60's, is a Master Mechanic, and has seen it all. Thank you Glenn for all the years of your great service.

Glenn has been our mechanic for 25 years. He is a true top mechanic, one of the most knowledgeable in the area. He is very ethical and an expert diagnostician. Glenn is equally adept at maintaining and restoring older vehicles as he is working with the newest complex technologies for cars of all makes. Glenn’s expertise in diagnostics, especially, means that you will never be paying for unnecessary repairs. Glenn manages every detail of his business himself. He is prompt and responsive. When you call his office, he immediately answers the phone unless he is doing test drives or picking up parts. A simple example of Glenn’s thoroughness recently: We have a 2000 Toyota 4Runner we have owned since new. After 23 years, it is still in new condition in great part due to Glenn’s care of our vehicle. It recently was leaving oil spots on the driveway, so I asked Glenn to diagnose and repair the leak. The oil was coming from a power steering return hose and front differential breather hose, but, partially due to all the spilled oil on the chassis, it was hard to nail down the source. Glenn took the 4Runner to the self-serve car wash and completely cleaned all the leaked oil from the chassis and engine. He did not even charge me for the car wash. 25 years ago, when I found Glenn, I had grown sick and tired of sloppy mechanics who charge too much for shotgun diagnostics. I wanted a AAA approved mechanic close to home and found Glenn. I am so glad I did. We have had several older cars that Glenn has maintained for us since new and when we finally sold them, we got way over Bluebook for the cars due to the thorough maintenance history Glenn provided. I can’t recommend Glenn more enthusiastically, and this long review only contains a couple of examples of all the ways Glenn has gone above and beyond for us. I have some older reviews on Yelp with more details of Glenn’s reliability, expertise, and excellence.Incidentally, Glenn has always been and continues to be a leader in professional organizations for mechanics. Part of that is he has made it a priority to support and mentor those who are seeking to learn and apprentice for careers as mechanics. I have met many of them. Haley, his current mentee, works daily with Glenn in the shop and is the best I have met to date.

I have known Glen since he started off. I worked gor Glen back in the early 80s. Glen I can say is not a rip off. He knows what he is doing. I haven't seen Glen in years and I have sent people to him and they all very happy. Their is more to the stories then what I have read. Craig Radcliffe

I recommend GDA Enterprises without hesitation. Glen has cared for both my cars for 20 years. His work is always top notch and he looks after my cars like there were his own. You never have to worry about his honesty. I recommended Glen to my daughter and afterwards she commented "how nice it is to find a repair shop that does the work right the first time."

I highly recommend taking your vehicles to GDA. Service is impeccable and the shop follows the safety rules for covid. I am able to send my newly driving daughter here and I know she is in the best hands.

Do not go to this rip off scamming place!!! If you want to be charged ridiculous prices for a problem with your car they can't even exactly diagnose, then come here! If you want them to not tell you exactly what you're going to be charged just to look at your car, then be shocked by the bill and have car held up before you can leave then come here! I've never experienced anything like this before. They quoted my husband $1700 to fix a problem they couldn't even pinpoint exactly. First sign of a scamming place. Then we wanted to go to another place for a second opinion, so they told my husband it's be $90 for looking it over. It's fine if he told us that from the beginning, but my husband signed something that said $0 on it, but apparently the fine print says he could charge $100 just to look at it. He could've just told us that verbally from the beginning. My husband has only one eye and is visually disabled, so it's easy to take advantage of a disabled person because you don't even have to tell them verbally that you will charge them and what the charge will be. Make someone sign something that day you owe $0 but in the fine print say you owe them $100 just to look at the car. Because they couldn't scam us out of $1700 because they figured since the car was towed, we'd be desperate to get it fixed at any cost, we'd agree to it, but we are not idiots! If I was there and could see the fine print, I may have picked up on the scam. All you have to do is be above board and tell us what's going on instead of sneakily putting it in the fine print, and could get a good loyal customer, but no, this place is really gross. It's places like this that give mechanics a bad rep. Please look elsewhere as there are good guys out there who will not resort to these nasty practices for a quick buck!!!
