Bought a motor from them 4 months ago n convinced me to put it there with them it took them only 3 days to put it on when i got it not evey a week n the truck broke down again then i told them they took it but it took them almost 2 months to pick up 🙄after they picked it up it took them 2 months again to "supposely" get another motor n we got it back last week w the other motor n still does the same thing 🤬🤬🤬 i think they just screwd me over because i took it w 3 mechanics and all say the same thing. Motor has not been changed only looks like the chains were replaced... i paid 1400 for the motor and 400 for mechanic plus when they came for it they charged me 40 🙄

DO NOT RECOMMEND!Went to buy a motor from them, I had to allow them to mount it for me in order to receive warranty. Well THEY DID NOT ADD MY MOTOR MOUNT! Had to find out from my mechanic after sending it to get checked after M&J did not want to help me and said I had no more warranty (when I only had 1 month with it and the warranty was for 3 months) showed receipt and all and still did nothing! I seriously do not recommend going to them.

Read before shopping or using their mechanic services (this place is no good) SAVING YOU TIME AND MONEY.First they didnt wanna sale me the motor unless they mounted it. So I gave them the job to do it. After mounting it. And keeping the truck for 2 weeks. The motor they had was no good so they had to other another took almost 2 weeks to get it. (Honestly I think they were trying to fix the one I had and lie about it). So they Supposably ordered a 2nd motor. Took almost same time to get here. Motor is finally mounted trucks works not so good. And now with a transmission problem.. this place is not even 1 star ...... went back cause now it looks like they even swapped my transmission...and as I went in,, there was already another customer fighting over coming back 2 time to try to replace a bad part they sold to him. That was no good. Also employees fight over their mistakes, and are very rude.

I was looking for a radiator. They said they had the part and to go by. I asked them to have the part up front. They said okay. I showed up 20 mins later. They said they were bringing part to the front. I waited for 15 minutes and then asked how much longer. They said about 10 or 15 minutes. I guess they didn't need my business... Just going to buy it new

Got my vehicle to be fix here for a new motor. They ended up crashing my car. Then they denied the car was damaged their and once I brought it up theyr covered it up saying it was already like that.

So much for warranty. Bought and transmission with "7k" miles and first gear never worked and 3 days later it started slipping. Now they won't take it back with there so called 30 day warranty. Wouldn't even credit me partial money back. $750 down the drain! Horrible company never use them. Better off buying new than dealing with this POS company.

This company is so unprofessional very rude customer service asking for prices and asking them if they have warranty they rudely said no and said (listen to what I’m saying if your buying this part you have no warranty and can’t return if it don’t work) And ask if at least we can try out and said no very ugly attitude and bad servicesI called other company’s and they were very understandable saying if one does not work we have other 2 you can try out for cheaper price as well

Working environment felt lazy, guys looked like they were dragging a**. Guy that helped me was on personal call instead of attending me. I also felt like they just throw “no refunds” in your face, as if they don’t want to deal with anyone. They couldn’t give me a receipt because they would have to charge taxes. I found that odd.

Was looking for an engine for my 2000 Silverado after flood damage to the engine. My mechanic at Andy Auto Service in Mercedes recommended M&J for replacement motors. Oscar at M & J hooked me up with a 2004 5.3L that was cammed with TSP Cam Kit for amazing price. Truck hauls a$$ now!
