    Fixing Oxygen sensor and misfire of 6th cylinder.

    The best and most reliable and affordable service for Porsches. Dod wonders on my 2008 Porsche 911 Turbo. Dives like new. Call Ernesto the owner and he'll do you Justice.

    Porsche 911

    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.

    Satisfied! My experience with HD is 100% pleased. Ernesto is a knowledgable and skillfull mechanic willing to go to anything length to solve and fix your vehicle needs. He loves what he does and for sure he will treat your car and you with the highest respect. I will not take my Porsche any where else.

    Carrera Gts
    Mr V.

    My Carrera GTS was in need of the major service at 30,000 miles. I have always serviced at that Rusnak Pasadena But since the warranty on the vehicle was over I didn't want to pay close to $3000 for that service at the dealership. So I started my search on Yelp Or certified Porsche service shop and I hadn't heard about the coupleShops near Pasadena that my friends had taken the car still but after comparing the prices HD Motorwerks Price was the lowest and of course the numerous positive reviews also helped my decision Visit Ernsesto at Hd Motorwerks . Service was quick, the vehicle what was inspected overall, and it was washed at the end as well. Will definitely be back in the future And will definitely recommend it to friends. Thanks very much for your service Ernesto!

    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.

I ordered a used replacement from eBay and after it arrived I looked for a body shop that could install it. After reading glowing reviews, I called Hyperion to ask if hey could schedule the installation, expecting to wait a few days. Instead the guy on the phone said to bring it in at 10:30 the next day. I didn't get there as a tweak in the door itself caused my overhead lights to stay on and drain my battery. I arranged for a friend to take me home, expecting to leave the car for at lrast the afternoon. But manager (I did not get hois name) said it would just be a half hour. He called over a ytechnician and 20 minutes later the car was ready! I had some body damage and the manager quoted me a price apologetically, noting that Lexus Parts are super expensive. I said well, it's a 15 year old car - probably isn't even worth the cost of the repairs. I started to walk away and stopped, turned and said, "Wait, I haven't paid you!" And he said, "no charge". I was dumbfounded and only hope I thanked him emough. Great work, fast, and even complimentary. I'm in awe. Go there!

Auto repair shops tend to be hit or miss if they do what they say they will, and this Shop excels in every way possible. When we spend as much on our cars as we do, you want to know that it is being taken care of behind closed doors, I can tell you without a doubt that this shop treats your car as if it was their own. TLDR; this is a car repair shop run by car people who love cars. Not only are they cool to talk Shop with, but they are very transparent and trustworthy.

    UPDATE: I posted a detailed review of my experience here last week. After being publicly visible…read morefor several days, it was removed on February 17th, claiming the content "does not appear to be my own." I'm reposting because every word is my actual experience as an 8-year customer, and other people deserve to know what happened. Eight years as a customer - huge decline since management changed I've been a customer here since 2012 when Chris was running things. Back then they were fair, professional, stood behind their work. That version of this shop doesn't exist anymore. I just finished dealing with Rubin on a repair for my 1989 MX-6 Turbo and I'm beyond frustrated. Here's what happened. The battery issue: I brought them a brand new Optima AGM battery from O'Reilly's - $300+ with the extended warranty because my turbo needs a quality battery that can handle multiple discharge cycles. They were supposed to fix the ignition switch that wasn't fully disengaging (which drains batteries). I specifically told them not to leave the battery connected while they worked on it for exactly this reason. They left it connected. Killed my brand new battery. When I picked up the car months later and realized the battery was dead, Rubin promised he'd work with O'Reilly's to get it replaced and call me back. That was 6-8 months ago. Never called. When I finally reached him again, he acted like that conversation never happened and offered me a basic Interstate battery instead. So now I'm supposed to accept a cheap replacement for the premium battery THEY destroyed? That's not how this works. Work that wasn't completed: My gauge cluster still doesn't work - can't see speed, fuel level, temperature. That was one of my main concerns bringing the car in. The radio they disconnected is still not working. The door lock they replaced fell down inside the door panel. I asked Rubin to either fix the cluster or refer me to an electrician who specializes in older cars. Said he'd get back to me. Never did. Condition when I picked it up: Backseat was completely disconnected and flipped over. Windshield was so dirty I literally couldn't see to drive home. Wires sticking out everywhere. Screws and washers scattered all over the floors and seats. When I asked why the backseat was taken apart, Rubin said "the mechanic needed to get back there." Okay but why didn't anyone PUT IT BACK? The runaround: First they said the ignition switch was the problem. Then it was the radio. Now Rubin says my car "just has electrical issues" and that's not their problem. Wait - I paid you $3,800 TO FIX electrical issues. If it still has electrical issues after you worked on it, then either the work wasn't done properly or you're not equipped to handle older performance cars. Rubin's selective amnesia about promises made, the battery situation, and the incomplete work has crossed a line. If Chris were still here this would never have happened. I don't know what Nick's involvement is at this point but Rubin is running this place into the ground. Eight years of loyalty and thousands of dollars spent over the years, and this is what it's come to. Really disappointing.
