I'm late to review Rob's, as they took care of me back in August, but these guys are amazing!!! Carter was the main employee I spoke with over the phone and he was phenomenal. He also came in on his day off to make sure I had … read more my car secured in a safe place until they opened. Corey also really helped when I came in personally and by going through some paperwork to ensure I wasn't being screwed over by the company I had been going to the last several years (which it turned out i kind of had been). Carter and Corey worked together to find me the best ways to handle the situation and have me honest suggestions without making me feel manipulated into paying for maintenance through they're company - they were there to help and make sure that I was safe while driving my vehicle. While being very professional and knowledgeable, they went up and beyond what I could have hoped for. The company understands that life happens and they do everything (within reason) to work with your time and budget to make sure that their clients are well taken care of and that the work that they do is thorough and accurate.I HIGHLY suggest using Rob's Automotive for your vehicle needs because of their honesty, hard work and their excellent customer service.Thank you again, especially Carter and Corey, for helping me get through a rough time with my little car and helping me feel confident that I made the right choices on how to handle my car issues. I will absolutely be coming back!
