great experience

They are excellent. They were able to send out my item as early as the next day. I am anticipating my product by early next week. Great!

Easy to order and a great price - look forward to receiving my parts!

Items were easy to find BUT the pictures for MOOG sway bar link were of Tie Rods. So confusing I had to call Tech support for clarification of my ordered parts.

Easy to use web site. Quickly found what I needed. Smooth check out and SUPER FAST delivery. Couldn't ask for a better transaction experience. Bookmarked and for sure "GO TO" for next auto parts search. Thanks Autoplicity

Ordered Monday - didnt ship until Thursday.<br><br>Email sent tracking number, but didnt mention which source was used for transport.<br><br>Product as described.

Autoplicity had fast shipping at a low price compared to other competitors. The price for the item itself was the lowest around so I think I got a good deal or my car. Would buy from again!

Pleasure to deal with, will use for future purchases as well.

Easy site to navigate with a nice GUI.
