I found Star Motor Werks through Instagram and I am lucky that I found this shop! I started following Geoff's page and I saw how knowledgeable he is with Mercedes... continue reading and especially AMG cars. I was having issues with my CLS 63 AMG and the local shop near me could not fix the issue. I'm in the Southbay area but I decided to tow my car to Costa Mesa to have Geoff work on it. Best decision I made.
Geoff and his team were very detailed and had great communication regarding the various issues he saw with the car. They took pictures and sent them along with their inspection results. After the work was completed, Geoff stayed after closing hours so I pick up my car. Even though it took me over an hour on the 405 freeway in traffic to get to the shop, I will continue to bring my car to him for service. Great customer service and attention to detail.
I've been meaning to write this review for a while now, and it's long overdue. I cannot emphasize enough how fantastic Geoff is. I've known him back since around 2010... continue reading when he was at The Auto Clinic in Tustin/Irvine and I've finally found him at his latest venture. If you own a Mercedes or probably any European car, this is the go-to place for top-level service and maintenance. Geoff, the owner, is an expert mechanic having spent years at Mercedes.
He takes the time to explain exactly what's happening with your car, detailing what needs immediate attention, what might need fixing in the future, and what you can expect down the line. I was pleasantly surprised to get updates with pictures/videos as the service went on. It's that personal touch that makes all the difference. It's rare to find such transparency and honesty in this industry. When you bring a car to Geoff's shop he treats you like family and you can rest assured that your car will be well taken care of. Highly recommend this shop!
I was very pleased with my recent AMG service by Star Motor Werks. Geoff provided excellent communication after a thorough inspection during regular B1 maintenance service. The team noticed certain... continue reading items that needed to be addressed, which the Mercedes dealership had previously overlooked. We mapped out a plan of what to handle immediately and what could be done later. Geoff's knowledge and honesty truly stood out. The prices are very competitive as well. I highly recommend Star Motor Werks for both regular maintenance and any performance upgrades.
Excellent service. I will be bringing my car back, they were so nice and helpful. It felt like I brought it to the family mechanic, they explained everything and had... continue reading friendly energy. I definitely recommend bringing your Benz here for service.
I took it in for the Check Engine light. A safety inspection by Star Motor Werks revealed some other issues that were not yet necessarily bad but needed to be... continue reading addressed. I agreed with their assessment and authorized them to take care of them. They did and even had the car smogged and ready to register.
I rarely update my review of a place, much less to reenforce a previously positive review, but these guys continue to prove how good they are. Geoff in particular is... continue reading always very positive, knowledgable and forthcoming with help. They recently did a full brake replacement on my 2018 GTR, was very smooth and I couldn't be happier with the results. As long as I own the car, if its not for warranty-specific work, I will only be bringing it here, even for regular services.
Talked to Geoff about my tune for my Mercedes E400. He was really nice about it and we talked about the options available for it. Also was surprised I was... continue reading able to get an appointment set up for it right away even was possible to fit me into the schedule the next day. He is happy to answer any questions or concerns and do his best too. I would recommend coming to him for sure! 🙂
Geoff made the process so easy, I ordered the parts and they arrived ahead of schedule and he got me in and out in 2 hours
If you have an AMG and don't want to get subpar service at the stealership or go to a shop that's not trustworthy this is the place for you. My... continue reading W205 C63 S started misfiring suspecting it's from a bad spark plug I took it to the stealearship and they couldn't even make time to plug the diagnosis computer for me. I called up Star Motor Werks and they were able to replace my spark plugs and coil packs the same day on a Friday with amazing service. definitely check this place out if you want quality professional service for you AMG and better value than the dealership.
Geoff is an upstanding human. He's personable, honest, detailed, and treats others even better than how he would expect to be treated.
As you'll see in other reviews, Geoff's clientele... continue reading are mostly AMG owners. I have a 2004 E320, which probably isn't even worth as much as the brake dust from the AMGs that Geoff typically works with.
Yet, Geoff treated me just as he would treat his other AMG customers, and provided the highest level of straightforward, personal customer service that I have ever experienced at a mechanic's.
Most importantly, Geoff's technical proficiency exceeds that of the dealer's. He accurately identified a number of discrete issues that the dealer had missed, and his advice and recommendations are, like his pricing, practical and honest.
Unlike some other highly-rated independent mechanics I've visited in the area, Geoff is not in the business of upselling any non-essential work. Instead, Geoff empathizes with and is able to view issues from the customer's perspective, even if doing so would be against his own pecuniary interest. As a result, Geoff has won my trust, and there's nowhere else I would rather take my car.
Thank you Geoff, and a special shout-out to Mr. Navarrete, for making my 2004 E320 run and drive like a 2024 E320.
I dropped my 2014 cls550 off for work due to leaking coolant everywhere Geoff and his team tackled my car like nothing extremely satisfied with the work and professionalism definitely... continue reading will be getting more work done by them 100%
Geoff and the team at Star Motor Werks were very helpful for service B on my G63! I'm looking forward to bringing in my other AMG's in the future. Glad... continue reading I was able to find a trustworthy mechanic that does quality work!
These guys are the pre-eminent German automobile repair shop in the entire South Lyon never edging years of experience automotive parts knowledge AMG fine-tuning and probably has the best pedigree... continue reading of independent repair shops in the entire Orange County area and unparalleled blend of experience mixed with positive automotive knowledge make this the one Sharp that rises above all of the rest highly recommended with easy parking the starter motor works experiences the pre-eminent service repair shop in the Southland for your AMG or a high-performance automobile

Best service for Mercedes Benz owners they honestly tell you the truth about what your car services needs or doesn't. From simple services tunes up or whole motor build they... continue reading got you! Never had an issue and trust their work. Better price than the dealer with even more better customer service. Definitely recommend them!
Geoff is great with helping you out and making things look nice. I had problems with a kit and he would find solutions to make it work at a reasonable... continue reading price. He does a great job for customer service and the service it self on the vehicle. Great and honest work from this small shop. If you have custom stuff he sometimes as well would send me picture updates of the parts he installed and let me say he leaves a piece of mind knowing the process as well. He is fast and and clean with his work very highly recommended.
Jeff and his team are the best of the best. I trust Jeff with all my Mercedes needs. We just did a rear brake service on my Mercedes E63s. I... continue reading got my car back the same day and we used oem factory parts. Jeff's prices are extremely fair and will take care of you like family. Thank you for everything!!!
This place is the ritz Carlton or Nordstroms of car care.
Amazing, friendly, and very reasonable.
Staff is nice and cordial and their workmanship is unreal.
There's nothing they can't fix and if... continue reading you don't need it, they won't do it.
Fast and reliable.
Highly recommended to all!
This place took care of me well and had amazing service. Came in for just a diagnosis and a couple hours later they not only diagnosed the issue but had... continue reading it fixed for a great price. Jeff the owner was very kind and patient with us and worked to get everything done efficiently. Sandra as well was very nice and patient with us. She not only offered me free pizza but later overheard me in a call hang up due to having low battery and came back with a charger without me even asking. These guys do amazing work at great cost while being very efficient and take care of there customers well. Thank You Jeff and Sandra! If any mechanics shop deserved a 5 star review it was here.
