They ended up replacing my battery super efficiently and gave me complete peace of mind. It's really hard to find honest, efficient customer service like this these days. Highly recommend asking for Montell or Bob!

Needed to speak to someone about getting a product to help with some scratches on my car. Cashier…read moreyelled for a certain man to help me..supposedly this man knew about this sort of thing and would help me. He was supposedly was leaving shortly to deliver some items and walked with me out to my car. It was pretty apparent that he just wanted to leave to do his delivery and was less than helpful. His suggestion was to buy some equipment to do it (this is a rental and I had no desire to spend a bunch of money) OR take it to a detailer. I said that a detailer will want to do a whole vehicle not a 1X1 area. He remembered he had to go back into the store and said he would show me what to purchase. We walked into the store and he pointed right and said "look in aisle 3, you will find what you need." Really?? That's it? This is the guy who knows?? I could have saved myself 15 mins by bypassing this less-than helpful person. I was looking for HELP...

I found these guys and got a reasonable quote. We worked around my friend's doctor appointments and drove from Brentwood to Tracy one morning. We arrived, hobbled in, (I was on crutches from a foot problem, he on his walker) and were immediately treated like royalty. The took the keys and whisked the truck away. We wandered around looking and asking questions about a variety of products they carried and before we knew it they were handing back the keys, we paid for it and went outside to see how the new cover worked. It looked great and operated fine. They even removed and disposed of the old tonneau cover for free. A great place to do business!

My 2012 Kia So was left 45 miles away after ubering home. I didn't even need to be with my car for them to diagnose and fix on the spot. They first came to me to get the car keys, drove 40 miles to my car, ran a diagnostic and was in great communication via text and phone calls regarding the situation. I also appreciated the fact that they were willing to try cleaning things first before jumping to the money grab. They also did a great job explaining what was going on, options and potential costs without being. Service really is guaranteed, they were willing to come out, no charge and run a diagnostic a couple days later to ease my mind about a light that came on. HIGHLY RECOMMEND
