The order was shipped promptly, and everyone was is good working condition. I will order from here again!!

This is our second order from Autoplicity. The first one didn't go so well due to a mix up with the Sparco seat pricing. Though I was starting to question our decision to order from them after several emails and phone calls and online chats, they came through in the end. These guys earned our second order by honoring the price they had listed and then calling to follow up when our race seat was shipped. Since this group was able turn our bad experience into a positive one we made our second order and, so far, it looks like they are again getting us what we want at the best price we can find. We are happy to recommend Autoplicty and plan on using them for future orders. There is one specific thing we would recommend, change the quality and volume of the hold music on the 800 #. It sounded like we were calling a 1970's van with a blown Jensen stereo turned all the way up,...

They have the best unbelievable prices and availability on all kinds of automotive products on the market and like I said the prices are great i will buy from here in the future

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