WARNING! PLEASE READ! PLEASE! I do not know what these guys are up to or what scam they are trying to run. They promise and promise and NEVER, NEVER, NEVER deliver on what they say. Everyone else on here is correct about the shop. If they tell you a day it would be a month. Mark and Stephanie try to be nice but they can't finish. And the basic maintenance that they did for me was faulty and almost caught my truck on fire. Do not come here, you will regret it.

Customer service from Stephanie was excellent. They took me in same day I had called and My Hino was ready the next day. Very nice people. Will definitely go back when needed. Price was reasonable also.

Had a solid experience here. The mechanic was straightforward about what needed to be fixed and got my vehicle fixed. The repair was done on time, and my truck is running well. No complaints!

If I could, I would give G&M 10 Stars! I am a returning customer here at G&M. I’m always provided with 10 Star service. I am updating my review because I believe Greg’s and Debbie’s honesty and Integrity should be known and rewarded. I recently brought my truck in for service. My truck is working great now. I get a phone call the day after I picked up my truck; and Debbie tells me due to new computer system, I accidentally got overcharged for something and they want to give me my money back. I am astonished with the level of honesty and integrity from G&M. I think most other dealerships would have just kept the money, but not here at G&M. You won’t regret choosing G&M. Thank you Greg and Debbie. Here is my previous review: Greg and his team took care of my 2007 Chevy Suburban. The truck would not start, was leaking oil, and had the check engine light on. I knew my truck needed a lot of work. G&M took care of it all. I live about 25 miles away from this G&M, but I brought my truck here because I trust their expertise, experience, honesty and integrity. Capri at the front desk is always very courteous and helpful. The truck is running great. Thank you

I had a horrible experience with this company (and have heard from people in the industry) that they have had similar experiences. First of all, they took about 2 months to get a simple part for a rental truck that we had them fix. I called every day for status updates since we were getting charged for the rental of the truck, and it was a mission just getting them to call me back (very unprofessional and rude). After they finally got this part, they said it was the wrong one and then they took an additional few weeks to get the right part. They charged our card for the full price of the service (way more then others have since quoted for the same work), but refused to give the truck back until we sent them a photo of the card and my drivers license. They said it was company policy to do so prior to taking payment, but this clearly was not true since they charged the card prior to asking for this. I ended up being an hour late to our company holiday party since they had this insane request and if I didn't do this, we would have had to had our driver (at our expense) come back on a different day. All in all, one of the worst repair companies I have ever dealt with. Very unprofessional, very rude, very incompetent, very slow, very expensive. If I could give negative stars, I would. Stay away!

Brought my RV in for some repairs, and they did a good job. Mark is a really nice guy that works there. The service was straightforward, and the pricing was fair. Everything was done in a reasonable time, and my RV is running well.

I first brought my Ford E450 ambulance RV to Mark and the All American Diesel team, and ever since, they’ve been the only shop I trust for all my vehicle needs. From routine maintenance to major repairs, their expertise and professionalism are unmatched. The team takes the time to explain every detail, ensuring you understand the work being done—something you don’t often find in other shops. What truly sets them apart is their commitment to their customers. One time, I ran out of fuel on the highway, and Mark and his team came to my rescue without hesitation. Their response was like a Navy SEAL drill—flawless, efficient, and executed with precision. They had me back on the road in no time, turning what could have been a nightmare into a smooth recovery. If you own an ambulance conversion, fleet vehicle, or any specialty rig, this is the place to go. Their knowledge, honesty, and dedication to quality service are second to none. Highly recommend! - Aliso Viejo This keeps it polished while naturally including “Aliso Viejo” at the end. Let me know if you need any other tweaks!

WORST shop i have ever taken my vehicle to. NEVER TAKE YOUR TRUCK HERE FOR REPAIR! Extremely disappointed with all the work that was done to my vehicle. Took my car in to fix a starting isuse. My truck sat at their shop for a months and I had to continually call and hound them to start working on it. When they finally did they would tell me one thing was the issue and I would pay for labor and parts and it still wouldn't fix the problem. After that happening multiple times they said I needed to replace my entire wiring harness. After tearing apart my entire interior, they damaged multiple panels and even lost my floor mats. It's been months since I have had my truck back and they still haven't given me a replacement. When I finally did get my truck back "running" they couldn't figure out why it was staying in limp mode. They promised they programmed all the new moduels that I paid to replace multiple times. I drove it home without power brakes,steering and check engine light which were all new issues they caused while it was there at the shop. I took it to a much better shop that actually knew what they were doing, they programmed everything they said they did and all lights went away and ran great. I continue to find more and more issues that they caused with my truck, cut wires missing conectors, unfinished work they half passed. MY WHOLE RESR SEAT WASNT BOLTED IN! Now I needed to trailer a car for work and they didn't conect my trailer brake system back up and there is no function to my trailer lights. WORST SHOP THAT JUST ROBS YOU OF YOUR MONEY AND LEAVES YOU WITH A WORSE AN EVEN WORSE VEHICLE THAN WHAT YOUR BROUGHT THEM!

just now New I took my Ford Transit Van in for a diagnostic The outcome was that I needed to replace the high pressure pump. Cost $5,000 , the truck will be ready 5 days. Mark is very believable. Over 10 days later I called to check and was told that I needed to replace the 5 injectors another $5,k+ plus and an additional 5 days. Two weeks later I called to check on my work truck that has been out of service for over 30 days I was told that I now needed to spend another $5k+ for a fuel filter etc . The story goes on and after spending almost $25k and 6 weeks , my engine light is still on so I have to go get a second opinion.

Beware of this shop, they ruined 2 of our trucks and charged us thousands. 1 truck still at their shop, refusing to release it back to us after charging us $7000. Look for a Ford F650 stakebed at their lot and you'll see yourself. Greg stated he had a replacement Block, after taking out the entire engine apart he calls back stating he doesn't have a Block. See the pics. Speak for itself. This is how they returned back to us after charging $7000. This is 2nd truck. Need details feel free to reach out to our company. Currently going through legal means to get this situated. They wont even send you an invoice before they charge your account. Forged our signatures on invoices. DO NOT GIVE THEM YOUR CREDIT CARD information.

I got tipped off by a friend to go to G&M after looking to put a lift and a locker on my van. I went to G and M and they turned my family van into the beast it is today. I drive places people in jeeps have no idea how I made it. Sometimes I don't even know how I made it but my van takes me wherever I want to go now. Thanks G&M for giving Freedom the van the steong soul it has today!

Do not take any vehicle there!!!! Theses people will smile while ripping you off!! The BAR of California has taken away thier shop licenses. Don't give them a debit or credit card they will charge it without your knowledge and take what they can before you even get a bill or your vehicle back. 8 months 12k later and I had to go to a different shop to get my truck repaired. Every time I take it back it's a new problem to fix the original problem I had it there for. Problems never resolved and they would keep my truck for weeks. You have been warned!!!

I had mechanical work done on my Ford F-450 at All American Diesel and Fleet, and the experience was excellent. Greg, is extremely knowledgeable and does high-quality diesel repair work. He took the time to explain the repairs and made sure everything was done right. Stephanie in the office provided great customer service—professional, responsive, and easy to work with. Communication was clear throughout the entire process, which made scheduling and pickup seamless. If you’re looking for reliable diesel repair, fleet maintenance, or heavy-duty truck mechanical work, I highly recommend All American Diesel Honest service, skilled technicians, and great customer care. I will definitely be returning for future diesel repairs.
