However the repair shop will still need to do their own diagnosis when you bring your car in & it'll be more thorough. Still helps since some repair shops are not always honest.

Two years ago I bought a premium battery from O'Reilly Auto Parts. Two weeks ago my car wouldn't…read morestart in the morning. Later when it was warmer it did start. This pattern repeated for several days. I asked ChatGPT what the problem was. "It is probably the battery," was the response. I asked Google Gemini. "It is probably the battery," was the reply. I took my car to O"Reilly Auto Parts. "Your battery is perfectly fine," they said. I asked them what the problem could be. "We don't know, but it is not your battery," they replied. I went to a mechanic. "You have a bad battery," he said. He replaced the battery and the problem was solved. Why did O'Reilly not tell me battery was bad? Because the battery was under warranty and they would have had to replace it. You have been warned. Stay away from the O'Reilly crooks. They have bad batteries and bad warranties.

I recently bought a 2026 Toyota Sienna and had the best experience with Zach. I had heard that…read moreSiennas were hard to come by, and a lot of other dealerships I spoke to were trying to get me to pre-buy before the car even arrived on the lot and I was able to test drive. Zach was super responsive from the very beginning and assured me that he'd let me know when the car arrived AND would do his best to give me an opportunity to come in and test drive before I bought. This gave me incredible peace of mind, and reassured me that these folks weren't going to use fear or pressure to make me make a purchase before I was ready. When I went in, Zach was super kind and helpful. He knew everything about the car, gave me tons of great tips about how to get the best out of it, and made the purchase an absolute breeze. My hope is that I won't have to buy a car for a while (gotta love a reliable Toyota). But if I did, I'd be right back to see Zach at Livermore Toyota.

I left there paying $200 for everything where I would have probably paid well over $125 or more elsewhere! Joe was really cool and takes pride in providing high level of customer satisfaction and service. I was impressed. He has earned my business for sure. Selection is nice but Fred said they could get anything. I will take up that offer eventually. So it is nice to be able to go to a place that can get me anything and take care of all my Jeep needs! Seriously, I just received t an incredibly cool, efficient and quality appointment at the 4x4 shop. So if you are looking at getting any 4x4 upgrades, mods, parts etc., head on down to The 4x4 Shop in Livermore, CA! You will not be disappointed!
