From the moment I met Jesse, I knew I was in great hands. Jesse is a fully equipped mobile mechanic who handled everything on the spot with amazing efficiency. He arrived right where we agreed, prepared with all the necessary tools. He completed the job quickly and right in front of me, explaining every step of the process as he worked. Jesse even checked if I wanted to keep the old brake pads and rotors or if he should dispose of them, which showed his conscientious approach and respect for my preferences. His workmanship was immaculate--everything was done cleanly, and honestly, my brakes don't squeak anymore. I can feel the improved stopping power immediately. Jesse's professionalism and attention to detail are unmatched. I was also impressed by how friendly and straightforward he was, making the entire experience very comfortable. I genuinely don't understand any negative reviews on his page, as my experience was flawless. Jesse is definitely my new go-to guy for any automotive work I need in the future. I'm very grateful to Groupon for bringing him to my attention because I probably wouldn't have discovered such a reliable and skilled mechanic otherwise. If you want honest, quick, knowledgeable, and affordable service, look no further than Jesse at Green Barrel Motors. Highly recommended!

I bought a break fluid oil flush voucher on groupon for mini cooper. Before I went to the shop, I…read morecalled the merchant to schedule an appointment with my car info and how it's working. The owner didn't mention ay additional charges. When I went to the shop , the owner told me I need to pay additional $40 dollars for oil recycling which is not mentioned on the groupon website. I told him I can accept the charge and I need the receipt with the $40 additional charge to follow up with groupon about it. The owner said I am not interested in the deal anymore and asked me to leave and get a refund from groupon. I also noticed the owner increased the break fluid flush price on groupon from $160 to $240 after I left the shop today. It's a really bad experience for customers that the owner can change his mind and reject the service. Update for owner's review below "a vehicle that is directly not covered in the advertisement" , groupon adversisement doesn't mention any special vehicle price. After the owner told me to charge additional $40, I was confused and later accepted the charge while telling him to get the receipt for reference then I can follow up with groupon. After that, the owner refused to do the service. I guess the owner don't want his practice to be exposed to groupon. The owner could have listed the additional charge on the groupon website in the beginning to let customers be clear about all the cost. " TheThe individual came in with a vehicle that is directly not covered in the advertisement. We told him it would be an additional $20 and there was also $20 for hazardous waste because the Groupon does not cover exotic Europeans he's on here acting like a child and leaving negative reviews I offered to work with him but he was combative and at that point we had asked him to leave do the safety constraints of the business and our employees.
