 Trustindex verifies that the original source of the review is Google. 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!

 Trustindex verifies that the original source of the review is Google. 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!

 Trustindex verifies that the original source of the review is Google. 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!!!
