I was little worried when I made an order, because the price was too good to be true, and Autoplicity was new to me.
However, Autoplicity took only a business day to ship my item.
The item has been delivered, and I'm very happy with Autoplicity and the item itself.

Thank you Autoplicity for the great price and fast shipping!!!
Autoplicity had exactly the part I was looking for, for my SRT8 Challenger, at the best price I could find!
Great site and service! Looking forward to doing business again soon!
Shipped out fast. Prices are very competitive. Couldn't ask for more.
