Site use was easy, and product shipped promptly after ordering. Price was the best I could find, would use this business again.

Wow. Ordered it on a Wednesday got it in 2 days....amazing....and to top it off my mandrel bent ss tubing was packaged infinitely better then I would of imagined. The price was amazing. I literally have no complaints. I will definitely order again. I will say that items on their website were not labeled well so I used vibrants website to look up part numbers so I could get the right parts. Search engine wouldn't bring up items via part number. Kinda confusing but for all I got simply awesome.

Lowest price on EBC brakes for my Subaru. Good speed on processing.

First I found Autoplicity through The Find, they already had the item discounted, other than all the other online stores where you needed to search for coupon codes. Then the transaction was very simple, they accepted PayPal which was the payment method I wanted to use.<br>I'm very happy with my purchase and the service I got from Autoplicity.

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.

Autoplicity has an abundance of name brand parts at unbeatable prices. Customer service was also great to deal with. Receipt and tracking info was provided promptly.
