Good so far

easy navigating

I am so pleased! Autoplicity had the best price by far for the item I ordered. I was not familiar with them so having the Paypal option was perfect. Over all I saved $30 on an item that was close to $100. Shipping was VERY reasonable and quick. I ordered my item on Saturday. They shipped it right away and I received it on Wednesday. I am definitely an Autoplicity fan and will recommend them to my friends not to mention our mechanic. He found the item I wanted on sale through another major company. Just to double check, I searched online and Autoplicity blew that company out of the water with their pricing and service for the exact same item. Very nice!

Ordered my parts on 4/18 and received them on 4/20. Very fast service! Would recommend buying from Autoplicity to anyone and everyone!

overall i was very pleased with the way this site compares to all others, but there is one disappointing aspect. There is no detail on part placement when the parts are listed before you click on them for more info, very frustrating in terms of user frien

great

By far the cheapest set of headers & x-pipe for my car on the market! They got them out the door first thing & sent me emails so I could track them. Very happy with this quality of service.

easy transaction so far

Very good prices.

Item was very good quality and arrived in 4 days great service.
