Was not the same as photograph. Very misleading.

nice to do business

I ordered a new latch for my center console and it fit perfectly. I could have bought it locally but the local store didn't have it in stock. I figured if it had to be ordered I could order it sent to my house.

I found the experience very satisfactory. I did find the website a little difficult to navigate and search to find items especially when looking for particular items in different sizes/quantities.

Great co

Good service.

Wow talk about FAST shipping...I placed the order...and the door bell rang for delivery!!! The electronic points and coil when in the FJ 4o in just a few minutes and work perfectly...THANKS so much! Larry in Montana

Unbeliveable customer service and super fast shipping. I had a question about my order and I was able to use the online chat function to instantly connect with a customer service agent that was quick to answer all my questions regarding my order. I am very pleased with the level of service I received not to mention the great price they offered on the item I purchased. I will be sure to continue doing business with Autoplicity for my automotive needs. Thanks so much. A+
