    If you're a Porsche owner/enthusiast in California, you've probably heard of SharkWerks (or even seen them in a magazine or two). In fact, across the US, Sharkwerks is quickly gaining much popularity in the Porsche community. Sharkwerks is NorCal's preferred stop for all of your P-car needs. Owners James and Alex run a highly reputable, much praised Porsche performance/tuning/repair shop. I take my 2001 911 turbo to these guys exclusively. They're really one of the only shops I'd ever trust to do work on any of my cars (especially since I'm even more sensitive with my Porsche). I used to do all the work on my cars by myself in my garage, but it's nice to know that when I don't have the time/tools/energy to take on a job on the p-car, these guys can knock it out for me. They do excellent work and even make recommendations on what I need/should do based on what they see on my car and what they've experienced first-hand on their own Porsches. That level of service is not easy to come by these days with new "tuner" shops popping up every day around here. I've taken my P-car to Alex and James 3 times now and am 100% happy with my experience at Sharkwerks. I'll continue to bring my business to them.

    What a fantastic tuner shop! It is a Porschephile's dream come true. Alex is just an incredible guy. I had the pleasure of talking to him over two years ago when I was first considering purchasing my 911 Turbo. After about 30 mins of conversation, with his sage advice, I pulled the trigger and bought it. I should have reviewed them at the time but forgot to do so. The other day, I had an issue with my 911 Turbo, and once again, he was able to provide me excellent advice over the phone. He took so much of his personal time to help me out without charging me a dime. Just a true enthusiast that happens to own a business he is so passionate about. I brought in my car, and he had it up and running in no time flat. Truly a class act. It is hard to describe how much over 5* I wish I could give (considering other 5* businesses I have reviewed in the past), but Sharkwerks deserves it. I am very thankful that a business that is nationally-recognized and reputed is within a 10 min drive. I give them my very highest recommendation.

    I was in NorCal and wanted to try to stop into the shop to pick up a t-shirt or hat. Ended up gettting a high performance Stage 1 tune that gave my German car more horsepower and torque. Eventually, got the t-shirt and hat for free. Thanks to Dan, James and Alex at Sharkwerks. I will definitely be going back to these guys in the future. Dan and James installed my ECU tune while I was at lunch. For such a world renowned company; they really make you feel like you're their primary customer of concern. Cheers to you guys at Sharkwerks Jeff

    Truly one of the best porsche shops in the entire world. Great staff, great products. Can't go wrong w/ sharkwerks!

    It's hard to find someone to entrust with your Porsche for modifications. These guys are honest and insist on doing things right.

My cousin's 2020 Nissan Rogue Sport had a faulty radiator fan, and Luis was instrumental in helping us find the right replacement. The customer service is exceptional and efficient. If you call ahead, they will assist you with your needs and provide a reference number for your visit. I can't recommend Allied Auto Stores enough for their great service and fast response times!

    Dear Walmart on Osgood,…read more I'm writing to both apologize as well as share my experience. I first off want to say, I'm really sorry for getting frustrated while checking out for my oil change. There was miscommunication and my emotions got the best of me. The person who gave me to invoice for my car from the beginning was really kind, and I didn't treat him with the respect he deserved by the time I had left. When checking out, another guy who I don't know his name tolls me I chose the wrong oil for my car and that I should have chosen synthetic. I had told the original person who helped me I wanted to regular oil for my car, a Toyota Yaris. So he did that. But because of this other guy who was around the counter when I checked out, he seemed like was just trying to talk down to me and blame me for "choosing the wrong oil" and accusing me of making a poor choice. This led me to ask if the wrong oil was put in my car. The original guy who helped me (again so nice) said that it was fine, but it prompted me to be concerned about whether my oil in my car was correct or if I just put in the wrong oil. Jedi the manager came over to talk, he seemed calm and nice. But because I was already anxious and concerned if I put in the correct oil or not, I came off unkind. All that to say, I'm sorry Walmart workers and auto care. Overall I had a good experience , the only reason I'm giving a 4 star is because that random auto guy that works there that told me as if I should be ashamed that I chose the wrong oil, and escalated a situation that was necessary. Again, sorry to Jedi and the original guy who checked me out.

    I am never going to this location again. I went today for an oil change and waited 2.5 hours there…read morejust for them to tell me that they cancelled my appointment. They tried to tell me there is ZERO oil left in my car and that's why they couldn't do it, because they don't want to be liable for my car if they damage the engine. They told me I'd have to put some oil in myself and then go back to them to do it. First off, I do not have ZERO oil left, there is still some left in there and my light did not come on so it was fine. Second off, I don't know how the hell to put oil in my car and that's why I went to them for an oil change....Third off, they didn't even call or text me that it was cancelled and when I brought this up, they kept saying they texted me and I showed them the text and it's clearly not there. They tried to make excuses and would not take accountability and then just walked away from me when I was telling them they should have called me about this instead of having me wait there for 2.5 hours for nothing. It was ridiculous and the customer service was shit. I have been going to this location for oil changes for years and never ran into any issues until today, but I will never be going back here ever again. I am adding more to my review because the store just called me to tell me that I owe them payment because they changed my oil for me. NO THEY DIDN'T. They refused to and that is why they gave me my keys and I went to another shop. They did not change my oil and are demanding payment from it. I am in such disbelief at this. They need to get their facts straight, they don't know what the hell they're talking about. I cannot believe they are trying to get money from me when they did not do any work on my car. I am in such disbelief with this whole situation.
