I recently needed head bolts for my 408 stroker motor that I'm building. I searched the Internet and Autoplicity had the ARP Head Bolts that I needed. Great price and quick shipping. Will definitely buy from again!!

Mazda cargo mat for the CX-9 SUV came within 1 week. Mat fits perfectly; just as described. Autoplicity had the best price listed for this product; we are very pleased.

Easy checkout. Thanks.

Great prices for the springs I got. Def. the cheapest around! Everything was fast and straight forward.

I have searched the internet for the best pricing on auto accessories and ended up at Autoplicity. I tried everything to negotiate prices with some supplies and still got the best pricing usins Autoplicity without any hassles or delays. My invoice number 9314 shows that I got a great deal thanks to Autoplicity. I will be a returning customer for my future purchases.

Almost a perfect score! I was pleased with the customer service but knowledge about their products warranties was lacking. Other than that, the representative that I spoke with on the phone was great. He was friendly and had a good overall knowledge of the products I was asking about. Pointed me in the right direction because I couldn't be happier with my bike rack. They had the best prices, lowest shipping costs, and my order arrived a day early. Great website to work with. I will definitely be doing business again and spreading the word about Autoplicity.com.
