Had a smart key that unexpectedly failed on my Mom as she was having lunch. Luckily, she wasn’t far away and was able to bring her the spare key. Called our local MB dealer only to be told that I would have to drop off the car for them to diagnose even though I explained in detail what happened. They wanted $325 just to diagnose the issue. Called another independent MB shop who was able to diagnose the issue (bad key) but referred me to a locksmith who would make a new key but that it would be an aftermarket one. That is when I remembered seeing videos on IG of Star Motor Werks and reached out. Geoff responded within 15 minutes and penciled me in the following week. Decided to make the drive down to Star Motor Werks simply due to the fact that they’d make a new key using OEM parts at an affordable price (compared to a MB dealer). They even loaned me their shop car so that I wouldn’t have to wait around as I needed to run a few errands.Couldn’t be happier with the service and professionalism provided by Geoff and RJ. Would happily drive an hour and half in the future should I need any major maintenance done on our MB. Glad their vids popped up on my IG feed as they are truly knowledgeable and trustworthy.

UPDATE:Greetings everyone! I just wanted to provide a quick update regarding this whole situation. Long story short it was a misunderstanding between Star Motor Werks and I.Geoff made numerous attempts to contact me as well as took time out of his busy schedule to chat with me about the specificities of project. Every little detail was explained and Geoff even provided his professional opinions regarding the equipment / pricing. He for sure knows MB like the back of his hand!Since the holidays are fast approaching, my brake upgrade has been pushed back a little. We agreed to meet in person in the near future and proceed with my project. I will definitely update y’all with a full review once the project has been completed.With that being said, I’m changing my review to five stars (since Geoff and the crew are trying their best to make it right!).ORIGINAL POST:I initially found Star Motor Werks via Instagram when scrolling through car stuff. I’ve been saving up for a brake upgrade. I reached out via Instagram (as advertised to on their IG page) back in December 2024 and received an automated response (see attached screenshot). Never heard back. Life happened and I forgot about it.Fast forward to a couple weeks ago… again another Instagram add for “Star Motor Werks” popped up when I scrolling through car stuff. I looked up their Yelp page and this time. Since I was already on Yelp, I decided to reach out via Yelp’s “Request a Quote” feature. I left all the details about my goals for the project.The following day, I was contacted by a very helpful representative. She asked for some additional information and advised that she would call me back with details / pricing. She mentioned, “Oh yeah, we’ve done brake upgrades before!” I was stoked!! That was on 10/12/25.Never heard back. I decided to followed up on 10/13/25, I was informed that the details are still being worked on.Again on 10/14/25, I reached out and got the same response. At approximately 5PM, I received a call from Geoff (I believe his name is pronounced as “Jeff”). Since it was an unknown number, the call was pushed to voicemail. Geoff left a voicemail indicating that the project can be done, but parts must be ordered. I called back within 5-10 minutes and missed him. He was out for the day. I asked the representative if i can call back to chat with Geoff and was encouraged that they’ll reach back out to me.The following day… nothing. I’m starting to get the point. I re-attempted to reach out again on 10/17/25 and… you guessed it!!… same response. Keep in mind, today is (as I’m writing this) is 10/25/25 and I’m still waiting for a response.I’m sure their work is good (based on all the 5 star reviews on Yelp and Google), but unfortunately for me… I never had the chance to experience that “5 star service”.Just a little bummed out about the whole situation. I mean, I got my hopes up and it came crashing down… hard! I’m a serious customer, needing help for a project and I’m not trying to waste anyone’s time. Makes me wonder, why all the adds and expertise content on social media but… can’t even respond to a customer?? Therefore, 3 stars for me… the representative was very helpful and polite. Geoff seems knowledgeable and knows what he’s talking about (based on the voicemail he left). But as mentioned above, I didn’t get to experience what y’all Google reviewers keep writing and raving about.

Just got my ride back from Star Motor Werks and it's running smoother than ever! The team was super friendly, explained everything without making me feel dumb, and even had my car ready a day early. Cheers to no more weird noises!

Excellent communications. Work is done in the time promised. Friendly staff.

I absolutely love Star Motor Werks! The entire team is incredibly knowledgeable and always treats you like family. This is the only place I trust with my Mercedes. They’re honest and transparent, clearly explaining what repairs are urgent and what can wait.When I was shopping for my second Mercedes, bringing in some cars for PPIs, Geoff went above and beyond, offering expert advice on which models to consider, which to avoid, and what common issues to watch out for.

Not only is Geoff a true professional he's also a class act, I had a very specific and obscure request that required extensive research. I feel most other shops would've given up or outright refused the job but SMW stuck to it and produced a beautiful result that was as good as I could've hoped for, and this is done while being very patient with answering my constant calls and questions. I would not hesitate to take my car here in the future, especially for jobs that require a special touch and high levels of technical knowledge and skill.

I was referred to Star Motor Werks by buddy of mine where I live in Fresno, CA. He told me that he drives 5-6 hours just to service his C63s and he won’t take his car anywhere else. I followed his advice and drove my car down to Costa Mesa and I rented a car from John Wayne airport back to Fresno since my car needs time to get all the services done!I did set up appointment with Denise and I told her that I have to see Geoff.. I saw Geoff and he greeted me and he was very polite and patient while I explained everything what my C63s edition 1 needs.What I like about Geoff that he listen to the customer before he recommends anything.All the minor issues that require attention to detail he was able to fix them that my local Mercedes Dealership couldn’t.He did many things, from basic engine oil, transmission & brake fluid as well replacing the spark plugs & gapping them since I got Renntech stage 1 tune.. drive belts, AC recharge, fixing the driver window and rear trunk, replaced car battery and update the infotainment system and few other minor things.I already have Renntech exhaust and exhaust valve monitor and I wanted my car to sound little bit louder. He recommended RedStar catted 200 cel Downpipes with heat shield.. let me tell what! Best mod that I ever done! Sounds absolutely amazing! This is a must for every C63 W205.I highly recommend Geoff and all his staff members as they know what they are doing and Geoff keeps you updated with video clips and explanations.I am ready to drive 5 hours for my next service just to do basic oil change! Thank you Geoff! Very happy customer!

Geoff and his staff aren’t only knowledgeable but super kind . He am a female and am always worried about being taken advantage of . Geoff not only videos everything done to your Vehicle, him and his staff also make you feel like family. I wish I knew more people so I could send them for this amazing experience. I think this should have a boss like Geoff and the professionalism of this company.
