Overall service was excellent and went very smoothly. I set up an appointment by phone to replace the battery for BMW X1 and they helped me on time. The staff were very professional, knowledgeable, efficient and honest. I will definitely come back for future services for my car.

Took my Porsche Macan here to get some regular service maintanance done and let me tell you that the experience was exceptional! The technicians knew everything about German vehicles and educated me a lot about my car. They were fairly priced and got the job done quickly. I recommend coming here if you want the job done right. No gimmicks, great price, great customer service, and experienced technicians.

Used them to address leaking coolant and overheating issue on my BMW. They immediately addressed my concerns and worked with warranty coverage. They were nice enough to inform or recommend I go thru the warranty covered by the dealer, knowing they can lose business but was looking out for what’s best for me and my car. They were very attentive to detail in helping me and specifying the issues on my car to make sure the dealer was well versed with my car’s issue. Their info and assistance is greatly appreciated and would definitely/highly recommend them for your European car needs.

This is by far the best independent BMW service shop I have been to. Hratch (the owner) and Joey were amazing to deal with. Took my BMW 328d for an oil change and fuel filter change and I am extremely pleased. Prices are very reasonable and needless to say I will never go to a BMW dealership again. For folks looking at servicing their German cars, I highly recommend this place. Thanks guys!

Wish I found you guys sooner. It would have saved me a lot of trouble and money. In the 12 years I have owned my 87 BMW L6(fancy 635csi)I have gone to numerous 'older' BMW specialists and unless it was a simple issue most were in the dark. Toby and the owner sourced and solved my problems quickly and at a reasonable price. Thank you. I highly recommend this dealer.

Brought my Audi in to replace an engine oil pressure switch that was giving me an EPC fault and 4000 rpm warning. The repair was done super quick and the cost was way way lower compared to several dealerships in the area. These guys are honest and professional. Highly recommend.

Customer service is an understatement. I was in tough spot and they went above and beyond to help me and they are absolutely trust worthy. They could have taken advantage of me but they did the opposite. They showed me compassion and kindness and true service when I really needed it. They checked in on me regularly - they even checked on me the night I drove my car home. They were willing to accommodate anything I needed and great communicators. Can’t say enough good things about these guys and they will get my business every time.

Bash Autoworx by far one of the “best” German auto repair shops in San Gabriel and Inland Valleys. Workmanship and service superior. Reasonable prices far cheaper than dealer or other shops. Hratch and Joey are very knowledgeable and personable. They maintain and service my 911, Q5 and 328i, won’t go anywhere else.

1987 BMW L6 I have previously written a very positive review of the Diamond Bar location. They fixed a problem with my alternator that no other shop could do. They recently fixed a problem with my auxiliary fan that also baffled other shops. Their prices are very reasonable and their knowledge of BMWs is great. Joey helped me in both instances and I am truly impressed with his knowledge and dedication to customer service....a rarity these days. Highly recommended.

Can't say enough great things about Hratch and Bash Autoworx. If you have any questions or reservations about this shop, reach out to me directly. Hratch is a magician with Euro cars.. He's got a loyal customer for life!

Joey and Bash Autoworx are a breath of fresh air when it comes to the struggles of finding a solid independent mechanic. When I first picked up my 981 Boxster 2.5 years ago, I was looking for a solid indy shop so that I would not have to pay dealership pricing. I ran across Bash Autoworx (and they are local to me) after searching for a while and seeing raving comments in the various Porsche forums. Fast forward three years and they are the goto shop. Incredibly nice, accommodating, does not upsell (as a matter of fact, talks you out of certain services), prices are more than reasonable, very knowledgeable, work done in a timely manner, and just....friendly. When I say talks you out of services, I asked them to confirm if the spark plugs had been changed (dealership said they had but no documentation). They pulled a couple plugs, took pictures and confirmed that they were not original OEM. They could have easily said otherwise. Work I have had done there in the past 2.5 years: 2 oil changes, accessory belt change, brake (fluid) service, X73 suspension installed with an alignment, and most recently diagnosing and then installing the two microswitches in my convertible top.

Had some regular service performed here on my S5. My water pump was failing and they took care of it. Way better pricing than the dealer.

Clearly, I can appreciate how a customer may have had a particular issue with a service or whatever the mindset. To be blunt, the service I received, (plus all the other customer’s that cared to post a review), from Bash is Top-Tier! In fact, the owner, Hatch (I don’t know how to spell his name), is seriously experienced with Porsche cars. Basically, he’s very cost conscience, professional, polite, timely and equally important during these times - practices protection from COVID-19. I’m extremely satisfied with the care my Porsche’s (in the picture) 911 S convertible W/red top and (not in the picture) Cayenne Turbo S receive from Bash! Excellent work Hatch…

I can’t compliment them enough. Really wanted to get my headers installed for the weekend. Even though it was last minute Hratch was able to squeeze me in. He even gave me his personal car to take home so that I don’t have to wait. He finished it faster than he promised. My oil level light came on and he topped it off for me for free. Now my car sounds amazing with more power. Had 2 friends with a GT3 and 718 Spyder book an appointment today for ECU tune, rotors, brakes, and Soul race exhaust installation. This is the shop to go to. Knowledgeable, great service, and fair price.

Performed a PPI for me on a 2005 Carrera S. Checked for bore scoring and inspected the carbon ceramic brakes and bilstein b16 coilovers. Very convenient, fast and professional.

I came in to get upgraded front and rear sway bars and end links installed for my MK8.5 Golf R. Joey at Bash Autoworx responded to my email quickly and gave me a good quote with a fair price for the install. The service was fast (I dropped my car off at 3pm and it was done the next morning). Overall 10/10 experience, I would definitely choose Bash Autoworx again if I wanted to install more mods for my Golf.

This is the best Indy shop for European cars. I was helped by Joey and he does not disappoint -professional, personable and honest is what you’ll also experience. I brought my MBZ S65 for service B, which took an 1.5hrs and the facility was clean, easy to find, comfortable and timely! I highly recommend this shop for your Benz, Porsche or BMW!

I’m very happy with the work the guys did at Bash. I had a 3” lift installed from Eurowise for my 2004 Porsche Cayenne. They were fast, polite, and when there were issues with the install they had instant solutions. If you’re on the market for lifting your Porsche, this is definitely the place to go.
