Ernesto is simply the best--I really can't sing his praises enough! We've been coming here for years and he ALWAYS does a great job. The work is incredibly thorough, consistent, and you can tell he cares and pays deep attention to detail. My 2008 Beetle is still kicking (and looks SO good!) thanks to Ernesto and his team! - 10/03/2022 

Brought Ernesto my 2015 GT3 for spark plug + oil change service. Cost efficient, and timely. I'll be bringing my 2015 911 Turbo S in as well. - 5/20/2022

Wanted to get my newly purchased 2003 Porsche 911 Carrera 4S looked at for any issues and had read about Ernesto and HD Motorwerks. 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. - 1/04/2022 

I came to Ernesto to help perform a PPI service and left extremely satisfied with Ernesto's performance.
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. - 12/24/2021 

I'm glad I found HD Motorwerks! 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. - 12/09/2021 

I love this place!! Took my cayman to get serviced and Ernesto gave me a great deal, he’s so sweet and professional I highly recommend this place!! - 10/01/2021 

This place is GEM!
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. - 7/31/2021 

Thoughtful and honest. I feel better about my interactions here than at any other Porsche shop I have been to. - 7/03/2021 

Best classic Porsche service center I’ve ever experienced. Very reasonably priced. Ernesto is super familiar and knowledgeable with all the ins and outs and quirks with the older Porsches. He also goes above and beyond like finding special parts at reasonable prices. 110% recommend! Would definitely take my 944 here vs the official Porsche service center. - 5/28/2021 

Awesome guys! Helped me out in a pinch and were very welcoming and honest! Definitely recommend them! - 5/25/2021 

I've been a customer of HD Motorworks since I purchased my Porsche. The customer service is excellent! The prices are unmatched & the overall service experience that I've received here has made me a forever customer. - 5/07/2021 

I've never found a nicer, more professional place to have my Porsche Boxster S serviced, on either side of the country! Ernesto is a grade A professional, and takes great care of my car, no matter what problems I'm dragging it in to have repaired.

I bounced around different Porsche garages in LA for years until I found HD Motorwerks, and have been a loyal customer ever since - just the best! Highly highly highly recommend. - 2/18/2021 

We were initially referred to Ernesto through our last mechanic who moved their shop to the next county; he was great, and we trusted his referral and met Ernesto.

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. - 12/24/2020 

Ernesto and Rusty are awesome! Brought our Boxster in a couple different times for brake fluid and oil changes and they're very fast and professional. They also vacuumed the carpets, cleaned the brake calipers and did a quick general inspection. They clearly explain any issues they find and are fair with their prices. Highly recommend!! - 11/14/2020 

I have been here a few times since I moved to Los Angeles with my older 911
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.
If you have a porsche in this area and you’re in need of any kind of maintenance or repair, this is your guy. - 9/25/2020

I had gone to a shop to get my 987 Boxster diagnosed and they quoted me an outrageous price. Might as well go to the dealer!!! So I searched for a good Porsche place and found HD Motorwerks. They were extremely friendly on the phone, diagnosed my vehicle and repaired it in one day. They were able to offer me a way better price and did the job perfectly without taking me to the bank. Ernesto is professional and you can tell he takes pride in his job. Definitely coming back!!! Highly recommend, small little shop, a diamond in the roug - 9/06/2020
