SO FAR SO GOOD

Ordered Tein lowering springs. Shipment arrived fairly quick. Overall process was great. Would order from them again.

Utilized customer support for question on particular item. Phone answered immediately, consultant answered questions and I was able to place order immediately. This second purchase was due to the initial experience. Will make future purchases from Autoplicity.

Website was a bit slow, but the prices were pretty good.

Very easy

Ordering was quick and easy. A lot of piece of mind being able to check out through Amazon. We'll see how the rest goes. (Shipment, correct product, customer service if needed, etc)

Truly easy, fast and great way to get vehicle parts.

So I have an old car. It's and 83, seven years older than me. I'm also a student so I don't have much money and need to make as many repairs myself to save money. I go out to the local pep boys and auto zone to to try to find a repair manual that is for my old model but it's not available. I check online and there are very few copies on line. Autoplicity had the right manual at the lowest price by a good margin. <br><br>TLDR; Autoplicity has EVERYTHING and at a cheaper price

Awesome!

Smooth so far good price.
