Bubba Squashing

Called on Sat morning, truck wouldn't start, Marty's schedule was full but had his Mechanic Jay come by at 5:30 and by 6:00, it was fixed. Very knowledgeable, friendly, and quick! Would of cost me around $1000 of i had to have it towed to a fix it shop. For a fraction of that , around d 1/5th, it was fixed and ready to roll. Will definitely use again amd will tell anyone I know that needs a reliable, fair cost, mobile mechanic that Marty's Mobile Mechanic is the ticket. Very impressive; 5 Stars!

Great company! Came out same day!

Maritza Wasden

I had a great experience with Marty’s Mobile Mechanic. I had called 4 other places trying to find a solution to a stressful problem and no one got back to me. But I’m glad Marty’s did! The problem was diagnosed fast and the price was reasonable. Would definitely call again!

Moiz San Miguel

I was in a really unfortunate and desperate situation when i was caught in a flash flood with my two kids on a saturday. We managed to thankfully make it out and had the car towed to marty’s. Initially marty was very friendly and filled me with reassurances. He told me he would potentially check the car the same day and if not he would have it expedited due to my circumstances (potential water in the transmission) and have it ready by noon on sunday and that he would give me a call back. He called me back later in the evening and i told him exactly what happened. He told me that based on how my car was flooded it would be most likely a quick fix. I was extremely relieved. After this point, communication devolved severely. He would dodge my calls and texts and when my wife attempted to reach out to him he was extremely rude and authoritative even though we had done nothing but inquire about our car. After great difficulty, and little to no communication, we managed to get our key back on monday and move our car somewhere else and got the quick service we needed. Based on other reviews ive seen and my own experiences i highly recommend staying away from this place. Marty made an already stressful situation even more stressful. Update: Since posting this, the owner has responded with personal attacks and hostile commentary. This is very indicative of the service and experience we had.

Camden Petrie

I called Marty around 7:00 he got out to where I was located and was nothing but kind and respectful. I was talking to him and expressed and interest in walking through the process of changing my battery and taking a look at my engine and he showed me what he was doing and taught me something I wanted to learn. Marty will definitely be my go to call from here on out was probably the most pleasant automotive experience I’ve ever had!!!
