    Was driving from LA to Mammoth for the 4th of july holiday. My brakes felt very weak the entire trip up so I decided to stop at the last mechanic before we headed up the mountain. That giu said he couldn't work on my 1972 vw bus and sent me to the next shop down the road, that shop was booked up for the week they said (yeah I laughed and left) so I go to the next shop and that shop also did not want to check my brakes, they told me to go to the German auto mechanic a few blocks down. Now I know what you are thinking "why didnt you go there first?" Well I didnt see them and I should have. Once I got there it didnt look like they were busy, but that still didnt keep one of the mechanics from getting under the bus in the dirt to check it out. Although he did some tightening of my brake adjustment he recommended I wait for the boss to get back..so I did. The boss came back put the bus on the lift and immediately started to diagnose and fix the problem. He managed to bleed my brakes and refill the brake fluid reservoir which fixed the problem. He was very fair in price and glad I found him and his crew. THANK YOU for helping me continue on my journey.

    I can't say enough good things about Jim Allen's shop. From the moment I walked in, I was treated…read morewith honesty, professionalism, and genuine care. Brett, the owner, and his helper Jared were both incredibly knowledgeable and took the time to explain everything they found without ever making me feel pressured. They serviced my transmission and also tracked down and resolved a fuel/air gap issue that had been causing problems. Instead of just throwing parts at the truck, they took the time to properly diagnose the issue and fix it the right way. It's obvious they take pride in their work and stand behind it. Finding a mechanic you can truly trust is rare these days, but Brett and Jared have earned my confidence. They were friendly, transparent, and communicated throughout the entire process. My truck is running great, and I won't hesitate to make the drive back for future service. If you're looking for an honest, skilled, and dependable mechanic, I highly recommend Jim Allen's shop. Thanks again to Brett and Jared for the outstanding service!

We narrowed the sound down to the transfer case and drove the truck to the Chevron in Mammoth. They put it up on the lift, and confirmed the transfer case and recommended Jim Allen's Auto-Matics in Bishop, CA. I called and spoke with Brett the owner of Allen's Auto-Matics. I made an appointment with him for Monday July 6th and delivered my truck to him. Brett also diagnosed the swishing sound and unfortunately for me, the Ram needed a rebuilt transfer case. What fast service, in on Monday, July 6, and out on Wednesday July 8. Thank you Brett for taking me in on short notice and getting me back on the road like a pit crew at a NASCAR race. We left Mammoth on Thursday, July 9 and drove 314 miles to SoCal without any issues. I highly recommend Brett at Jim Allen's Auto-Matics in Bishop, CA.

I brought my Audi in to Shorty's for a routine service and to see if Rob could help me out with the catalytic converter codes I'd been running. The Audi mechanics wanted to replace the catalytic converter and the o2 sensor, which would've cost several thousands of dollars. Rob was super honest and upfront with me about Audis not being Shorty's bread and butter, but that he could help by giving it a diagnostic, figure out what things needed attention, and decide if it was time for me to shop around for another car. In the end, he recommended that I shouldn't default to replacing the cat or the sensor and hypothesized that it was a vacuum leak, also putting together a list of priority items--which Nicole explained in detail--for my independent euro car mechanic in San Francisco to go through and replace with Audi parts. My mechanic in the city read Rob's report and agreed with everything, remarking at how thorough it was. It turns out, the car did indeed have a cracked vacuum hose. He used Rob's notes to fix all the other little things that needed attention, and now I'm back to having a perfectly running car with 160K miles on it. It's really nice to have a shop out here that can pinch hit for this kind of troubleshooting and, even if they prefer not to get into some things themselves, provide a real honest and detailed diagnosis of the likely causes and solutions are. We're lucky to have them.

They just earned a new customer! They were very knowledgeable on the phone and instilled confidence immediately. They said they could take a look at my car if I brought it by.

But a couple of weeks is a long time to wait. They were just so above And beyond on my expectations at Shorty's. I'll never think twice about heading there again.

Unfortunately, I can't say the same for the rest of the service department. Maybe oil changes and routine maintenance are their specialty. But when it came to diagnosing the check engine light on my 2006 Prius, they completely missed the mark. My Prius threw a check engine light while I was on a road trip up Highway 395. I had it towed to Perry Motors. They said they fixed it, but thankfully I took it for a test drive before leaving because the check engine light came right back on. I got charged a diagnostic fee - fair enough. They couldn't diagnose the problem and kept insisting it was an oil issue. The problem? I'd already had the oil changed at another Toyota dealer before the trip, so I knew that wasn't it. To make matters worse, another service manager actually told me, "It's OK to drive with the check engine light on--we do it all the time." I found that advice pretty disturbing  I finally took my car to J&S Automotive, where Juan Santana worked his magic. Juan is a true car whisperer--thorough, intuitive, and someone who genuinely cares about getting to the root of the problem instead of guessing. More than 400 miles later, my Prius hasn't missed a beat.  Moreover he did not charge me a diagnostic fee and took me in right away despite it being the 4th of July weekend His shop is busy and plastered with incredible reviews and I can see why he is fondly known as Saint Juan Santana - patron saint of car troubles on 395! Would I recommend Perry Motors? Sure, for basic maintenance like oil changes and routine services that follow the handbook. For real diagnostic work? I'd skip Perry and head straight to J&S Automotive.

No problem, he wanted to offer buying the parts which I said great if it save me money. I it's the parts he broke during the repair and his inflated cost of parts which where higher the listed price on the auto parts web page he did something to the electrical which he had to bring in some other guy to help on top of having no car for over a week due to his inability to make repairs without causing more damage and time. I was so fed up I was going to have a tow truck come and pick up the car from his mother's house where he works or whatever. So finally he says come get it and it's running and gets worried I won't pay him.... Why would I do that after being hosed for a week. Anyway I did pay him his over priced parts cost and broken by him parts cost and labor requested. However now after getting my car back he left the battery strap sitting on the top of the motor.... Literally!! And he left other parts in the engine compartment and to put it on top this guy takes my two month old battery out and puts in a battery that only hold a 39 percent charge and would not return my calls today so I just spent 300 more today. I will be letting every know if he pays me for the new battery I just had to buy or not and that will determine if he gets taken to small claims court for this entire mess. Read the Google reviews!!!!! I wish I had. Happy some of you seemed to have gotten what you payed for...... oops forgot the final kicker charging me for two gallons of Coolant and my reservoir is empty??? Makes sense based on my experience with this guy. Don't make my mistake.
