ECS is my go to for anything BMW ECS is my go to for anything BMW. The parts are generally reasonably priced, some great deals come around, and you can get some really quality products. Their staff is ALWAYS helpful with questions and guidance. Never been steered wrong. I get parts for my 1985 535i, 2007 Z4MC, 2007 X3 3.0si, and the 2014 X5 xDrive35i - so their continued support of old and new cars is really important to me.

Great service and fair pricing Great service and fair pricing. Love the lifetime warranty.

one-stop shop Really one stop shop for my vehicle parts, really loves to shop around.

Don't rely on ECS Tuning application guide Based upon website guidance, I ordered an auxiliary input wiring harness for my 2003 Mercedes C240. I received it, decided to do some online verification before opening the package. I learned this harness wasn't compatible with my car's wiring. After a lot of hassles I was authorized to return it. I paid shipping both ways for a part incorrect for my car, despite the website claim it would work.

Great Customer Service Purchased some amazing well built items for my MK6 GTi i had some issues with the parts that I had ordered. Upon installation these parts didn’t fit , and after a lot of emails and pictures as I am based in the United Kingdom , the customer service team did their best to help come up with a resolution and will happily recommend and purchase from again. Keep up the great work
