Simple to execute. The order came unbelievably fast.

Easiest and fastest checkout ever!! :)

I looked all over the web for the Thule sidekick car top carrier and autoplicity had the best price and the website was easy to maneuver through. It willbe my first stop for shopping.

Easy site to use and nice connection to Amazon.

easy shopping

On line ordering very easy. Called before hand and customer service was great.......

Vastly overpriced, but I cannot argue with smoother shifts and reduced trans noise. Really feels like an upgrade.

Easy ,fast ,and secure

quick and easy so far, hopefully shipping will be the same.


You are the best price.

Wow, cheapest price I could find anywhere. AND, it shipped the same day. Amazing service. Thanks Autoplicity!

I needed to verify the part was correct. The telephone staff was very helpful, professional and informed about your products.

Great web design. Easy ordering!!!
