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.

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.

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.

Garbage parts Bad customer service Garbage parts. Defective and cheap spoiler. Looks like junk on the vehicle. If your past the return window good luck getting a replacement! Their lifetime warranty program is JOKE. You basically have to pay for the defective part a 2nd time to replace it and all they do when they get the part back is give you a in store credit. I will NEVER USE THIS COMPANY AGAIN!
