Did an Outstanding Job
"MJM Engines did an outstanding job on getting my 2007 GMC Envoy engine rebuilt and back on the road in a timely manner. I could've scrapped the SUV and bought another...but the vehicle was in great shape (other than the blown engine). My decision came down to whether or not keeping it made financial sense (after factoring in the total cost of repair, car rental, time, and inconvenience).

Drew provided excellent customer service throughout the whole process and he maintained the quote that his boss (Mike/MJM Owner) had given me over the phone. Drew kept me aware of what they were doing during the repair process and identified options available to optimize the performance of my engine. The total cost (including some upgrade options that I agreed to have done) were "significantly" more affordable than various estimates I received from the OEM dealership and some other local competitors.

To be honest, if I were to look at MJM Engines from say a local competitors perspective...I could see MJM's niche in the auto service market as an opportunity to enhance my own business by simply farming all my engine rebuilding work out to MJM.

Odds are...just by providing my customers that added convienence along with an unbeatable price and warranty, I would potentially preserve their loyalty and future business. I guarantee the OEM dealership that I stopped by first missed this opportunity and lost any future business from me.

I will be refferring friends, family, colleagues, and business associates to MJM Engines for years to come."

Very Fair and Awesome Work
"There are a bazillion very capable automotive shops in San Diego County but after some comprehensive research, I chose MJM Engines to rebuild the engine in my '64 Chevrolet C10 pickup. I was impressed with their operation; most notably their own in-house machine shop, skilled machinists and their remove & install services. Knowing that engine components wouldn't be farmed out to an outside machine shop was comforting. MJM Engines did an excellent job in installing and fine-tuning the new engine. Drew, the manager was the consummate professional and very thorough; always keeping me apprised of project status and never tried to up-sell me on products and services that I didn't need. Also, their website is very informative on their products and services. I would highly recommend MJM Engines to those looking for a trusted engine rebuilder."

“I had an engine replaced in my 03 Honda by MJM Engines 4 months ago and it runs great I have even gone back to them to try and have my brakes fixed but they don't do that kind of work.I'm very satisfied I mean I didn't like spending the money but my car works again.”

Highly Recommend
“If you’re in need of an engine go see MJM Engines. It’s been about two months now since I had to have the engine repaired in my jeep. Took them about two weeks. They called me let me know when they had the motor out what happened to it. No problems when I picked it up no leaks, or noises I think it might work better now then it ever has.”

Honest with Good Workmanship
“I rate MJM as honest with good workmanship. They work hard to please the customer. I took my 1964 Chrysler in and they rebuilt the engine. Great care was taken of the entire car while in their care. I am very happy with the over all experience. They will work with you and keep you in the loop. All machine work is done on sight except for turning crank bearings and the like. One man Roger does all the head work. He is easy to talk to and very informative. They clean, inspect and replace any worn part or any part you want replaced. Mike M is a gear head in the best possible sense of the concept. He had to scout up a lot of good replacement parts for this 50 year old MOPAR. Their price is very reasonable. Shop around; I did and you will see what I mean.”

Far And Beyond
“I was on a vacation to San Diego taking my wife and kids to camp at the beach . We were almost there when the motor in my truck started to knock . Not sure what to sine i was from Arizona I looked up on my phone and found this shop. I called them they told me i shouldn't run it anymore and have it towed in they gave me a number to a towing service. i brought it in they checked it i was very low on oil not sure why I checked before we left any why they removed the motor rebuilt it it needed a water pump and a radiator i told them i needed to get it back within five days so we could return home they got the job done in time and it runs great . they went far and beyond in my opinion.”
