I was hesitant to order from Autoplicity due to the perception that the price was too good to be real (and not some scam). However, I read a few reviews on the internet and decided to take a chance. Once I placed my order I was sent a tracking number and received my car parts within 2 weeks. I was happy that I got the parts I ordered and the price was really low. Simple and quick.
