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.

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.

So this company has no clue when your… So this company has no clue when your product will arrive to you once you buy something. I bought a John cooper works pro exhaust kit April 11,2024 and to this day the 25th is hasn't shipped and the expected shipping day changes week after week. The website says your item typically ships by the 3rd business day completely false. I've also asked for a refund which they never honored they gave me store credit..why would i want store credit to a company that takes months to deliver anything? Am I ordering from Japan? even they would have better ETA's this company suuuucks. Each person i speak with just lies oh yea it should ship on the date website says so, i call in next day its been changed again. It annoys me that ECS comes up on the net first when I'm searching to buy car parts because of how inefficient they are.

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

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.
