A very satisfied customer Placed an order through customer service. When my parts came it was the wrong parts. When I called to explain, the customer service representative was incredibly helpful and corrected my order and sent the correct parts at no cost to me. I cannot go wrong ordering parts through ECS. They're experienced, courteous and always willing to make their customers happy.

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.

Nothing about this transaction went… Nothing about this transaction went well. Ended up buying elsewhere, saving $300+, plus free overnight shipping. Weekend staff online worthless to solve issues. update; BS. I was asking why my payment was not processing, why I had no bonus points, why I could not use the $25 off (which processed the last time I tried) and why I always have trouble signing in... you should at least have read the text. But guess what, I'll probably still have to use y'all since you have bought everyone who supplies BMW parts, etc.

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

superb as always i have been using ECS for years and they always deliver quick and a very friendly staff. I have never had an issue with any orders and all the parts were as described.
