great pricing and fast shipping

Hassle free!!!

My initial review was 1 star because I ordered a Thule rooftop cargo box, but cancelled the order after Autoplicity called me about collecting extra money to ship the item after their website did not charge me enough for shipping. After my initial review Autoplicity offered to ship the item totally free since the issue was a flaw in their website. This was unexpected, above and beyond in my opinion. I have yet to receive the item but commend Autoplicity's customer service

I was looking to buy a gale banks header for my jeep. I came across this site th eir price was nearly $100 cheaper than any one else. Fast shipping too. Thank you.

Did not receive a confirmation email when I placed the order so I was unsure if if the order had gone through properly. Part shipped the day after I ordered it. I received three confirmation emails at the that time for some reason. Overall I would say the experience ordering from Autoplicity was excellent and inspired confidence.

Product arrived fast and as described. The best price I found online. Packing was excellent, highly recommend Autoplicity.

Great Company. I needed a part quickly and for the right price. They had the best price on the internet, and made sure it got to me in two days before I went away on my road trip. I spoke to a representative that was very helpful. I highly recommend Autoplicity! Thanks!!!

Great site! Just what I wanted!
