Gary's never did any work on my vehicle, because I called Gary's to get a quote for some work I needed done, and to my amazement, Gary told me that it would be a pain the ass. I clarified that he meant that it would be a pain in the ass to give me a quote, and he said that was exactly what he meant, because he would have to look up stuff! Oooooook! That kind of bluntness still has me laughing, but he clearly doesn't need any business, so I recommend you take your vehicle to a place that will respect your patronage! From my experience, that is clearly not Gary's. No other mechanics that I spoke with had a problem giving me a quote, and I have selected one to perform the work I need done.

We needed a smog done on short notice--I did a quick Yelp inquiry, the shop owners/staff messaged back quickly, and the next morning we dropped in. Went in Saturday morning--the (covering) technician was courteous, friendly, and professional all around, and we didn't feel intimidated as maybe you would at other shops. The technician (we didn't catch his name) was also very transparent, as he advised us on searching how to properly "drive cycle" our vehicle in order to reset the monitors after the first smog attempt read: "monitors not ready" -- DRIVE CYCLE? Yes, we learned something new that day! We prepared our vehicle to sit overnight, then did the drive cycle early Sunday morning right before returning to All Star Smog for the retest. Same technician was there and helped us out right at 9am. He also gave us a friendly recommendation for additional DMV services that we needed to complete. We all know that car services can most of the time be dreadful, but I can say that this was my best ever smog experience, between CA and NV. Thank you, All Star Smog!

The Chevy dealer said it would be a minimum of $1,000 to just replace the wheel, and that I'd probably also need to buy one or two tires (about $400 each). I wanted a second opinion hoping for a more affordable solution and a coworker recommended for me to ask Rocky at Napa Tire Experts for help. He was able to quickly identify that while the wheel was indeed cracked and could not be repaired, the tire was undamaged. In the end, they got me back on the road for less than half the cost of the dealership, and were honest about the fact that I didn't need to buy any tires. Rocky also took the time to explain to me what types of tires work well on electric cars so that I know what to look for when I need tires next time.

I was recommended here by my doctor, who said " this is a great place with friendly and honest mechanics! It's hard to find people you can trust with your car, but these guys are definitely people you can trust." And honestly I couldn't agree more. I came in to get a smog, Jabbar had me in and out within 15 minutes. I made an appointment the next day for an oil change. I arrived a little early, they took my car in and had it out before my actual appointment time! They gave me a free brake inspection and topped off all my fluids. These guys are very honest, friendly, and provided quick service! I will definitely be bringing all my cars here and I recommend you all do the same! read more
