    My car needed both low beams replaced, an oil change and a tune up. Matt was quick to provide me…read morewith a quote that was reasonable. Scheduling the appointment was easy. Brought my car in, went over some paperwork and was told I'd be contacted once the inspection was complete. Sure enough Matt called me to let me know there were some items found during inspection and which ones needed to be addressed right away. After agreeing to the updated quote they got to work. I came back to the shop prior to being told my car was ready, and I think there may have been a delay in getting parts needed (dropped the car off at 9am, wasn't done until 4pm). Other than that, the quoted price is what I paid, there wasn't any pushing to buy a service that wasn't needed. I will definitely be bringing my car back for the additional work needed.

    I requested a quote through Yelp and my request was sent to multiple auto shops. I chose this…read morecompany based on location and called ahead to confirm they could do more than just read basic codes. I had already done my own diagnostics and knew the car was running rich. I had ruled out the upstream O2 sensor, catalytic converter (both new), MAP sensor, and fuel injectors. I explained all of this to Matt before bringing the car in. He assured me they could perform deeper diagnostics with their equipment. After dropping off the car, Matt called and told me they had "confirmed" exactly what I had already told them, and that the next step would be pulling spark plugs--for an additional fee. At that point, I decided to go elsewhere. What I don't understand is why I was still charged the full $85 diagnostic fee, plus a $4 hazardous materials fee and $3 shop supply fee. Plugging a car into a diagnostic scanner does not generate any hazardous waste--no fluids are drained, no chemicals are used, and no parts are replaced. There's nothing about a basic scan that would justify a hazardous materials charge. That kind of fee typically applies when disposing of things like oil, coolant, or other regulated waste, none of which occurred here. In the end, I paid $92, wasted time and gas, and learned nothing new. The most concerning part was Matt admitting he didn't even know spark plugs would need to be checked as part of further diagnosis.

    I honestly cannot say enough good things about Albert. He is one of the nicest and most attentive…read moremechanics I have ever met and somehow he is always available even though it feels like he is working nonstop. That kind of availability and dedication is rare these days and it is one of the main reasons I keep coming back. I have taken my car to him three different times now and each time I have left completely satisfied. The first visit was for my brakes, the second time he fixed a leak in my steering fluid, and most recently he repaired an issue with my motor. Every single time the price has been more than fair, the work has been done correctly the first time, and my car has run perfectly afterward. It actually took me until my third visit to finally write this review because I wanted to be sure that his consistency and service were not just a one time thing. Albert has proven that he is reliable, hard working, and takes pride in everything he does. This is exactly how a business should be run and it is clear that his focus is on taking care of his customers. Albert is an older gentleman and I genuinely hope he keeps working for many more years because I feel lucky to have found my go to mechanic. I plan to keep my gas car until I switch to another Tesla and until that day comes I know exactly where I will be taking my car for service. I highly recommend Albert to anyone who wants quality work and a mechanic who truly cares.

    After driving around trying to find a place to smog my car, I found Ultra and couldn't be happier…read more The service was great and everyone was super friendly. Definitely going back for my next smog.
