They had my car for a day and called to explain all of the issues they found. After going through everything, we decided what should be taken care of right away and what others that could wait that were less critical. Ernesto did all the work we agreed on and listed the other items we didn't complete on my invoice that needed to be completed in order of criticality. He got all the work done in a timely manner and for much less than the dealer would have charged. He definitely knows Porsches. read less - 1/04/2022

He helped settle any concerns I had for my 400mi drive up North to the Bay Area.

He was detailed and personable, and was accommodating to questions during the test drives.
He spent the time to educate me on topics I did not know or understand.

I highly recommend Ernesto and crew at HD Motorwerks for your automotive needs. read less - 12/24/2021

Other Porsche mechanics I've tried in the area act tend to act like they're gracing you with their presence whenever they correspond with you, but Ernesto has been nothing but friendly, professional, and (most importantly) an all-around excellent mechanic. If you have a Porsche, get it serviced here. read less - 12/09/2021

Had mostly bad experience with rusnak porsche since 2015 when we had our first porsche, the dealership is too small and too busy, and so they always run out of loaners and repair schedules were always delayed. Whenever we raised an issue their first response is always that the customers are paranoid and didnt know how porsches work..and cars always come back filthy and uncared for. Over the years we started adding boxster, 911s, gt3 etc. so we started to try a few indy shops around town. Places like House Automotive provided great service but the price is the same as the dealer, which is probably as high as you can get. Others are so busy everything's by appointment, no followups and they expect you to just drop off your car sitting in the sun and gathering dust (which i hate, being OCD). Often times you cant even reach the mechanic himself, but all conversations are handled by a receptionist who cant answer any questions. And I am sure we all ran into mechanics who dont really care about your business and they sound like you owe them money....
That led me to HD Motorwerks, saw them on yelp and called. Went over the issues I had on the phone and they had availability to look at it in the next 2 hours. They gave an initial estimate which was lower than others, and with the faster response, decided to give them a try. Arrived at the shop a few hours later. The shop was pretty clean which was a very nice sight. They had quite a number of cars blocking the bays, and yet they remember that I called earlier and without hesitation started moving cars out of the way and got my car on the lift to start the diagnosis. Long story short, we thought it's something simple but we spent about 3 hours diagnosing the issue together until closing time and eventually decided we had a faulty part and has to come back another day. What impressed me is Ernesto's attitude and positive energy, he's always smiley-faced and despite the difficulties we had in the diagnosis he kept trying different ways to approach the issue and giving off a very positive vibe. His assistant has an extremely nice personality as well, always offering water etc. and is very careful around the cars. I dont see that at all in other mechanics, at least they certainly dont spend 3 hours doing that with me right next to him. With half a dozen sports cars of all different brands, I have seen quite a spectrum of them. In the end, the diagnosis he charged me is more than fair and at least we got to the root of the problem. At that point I know I have found my porsche guy (for the 911s and GT cars), someone who's honest, trustworthy, knows what he's talking about and yet doesnt have an attitude about it like a Mr Know-it-all, is respectful, positive and pay attention to details. I returned a week later with a warranty and had him take care of all the other issues I had with the car.
I told him about my OCD and what to look out for, he took notes and actually paid attention to my request. The repair took about 2 weeks, with the warranty inspection and waiting for parts etc.,all the meanwhile Ernesto kept me updated about the progress. Before I pick up my car, Ernesto offered to wash it, I asked if they do it in house and they said yes (many places send cars to other places for quick car wash and sometimes end up with scratches or blemishes that's hard to trace due to different locations and personnel handling the car, with inconsistent quality). I let them do it and when I picked up the car, it was spotless! the interior was clean and dust free and had no odor. No hand prints on the steering wheel or leathers. Dealerships and other mechanics have lots to learn from this place.
I highly recommend HD motorwerks as my go-to porsche guy, and more importantly, I hope they keep this up. With their customer service and performance I am sure they will get way busy soon. read less - 7/31/2021

Now, about 5 years or so later, we couldn't imagine going anywhere else. It's very hard to find a mechanic you can TRUST to not just fix your car's issues, but effectively and honestly distinguish what absolutely needs to be fixed, what should be fixed soon, and what can wait. Why? Because it's in their best interest to milk whatever they can to those of us who know little about cars (like me). I've had many bad experiences with other mechanics that exemplify this.

Ernesto, is not like that. Not at all. He's super nice, friendly, and humble... and he's highly adept, experienced, and professional at the same time. He's great at presenting options, keeping track of your cars health, and remembering off the top of his head incredibly fine details about your car. He thinks like a doctor, he genuinely CARES about his customers, and I just wish there were a lot more mechanics like him in L.A. read less - 12/24/2020

Ernesto was very thorough and attentive to the needs of the car and far more reasonable in pricing than shops in the area.
Over time he has taken my car from a decent car to an excellent example of what the quality of the brand is known for.

He accommodated my need for a next day PPI even though he was extremely busy at his shop. His PPI was extremely thorough and very complete. I ended up purchasing the car. Two separate Porsche mechanics (experts) reviewed the PPI report and were very impressed. My Porsche mechanic at home in Florida commented "you sure got your money's worth.'
