I bought an Exedy Organic Clutch at the best price I could find. Shipping was also prompt. Legit dealer, good business.

WHOA!!!! Best price around! I ordered on a Friday night and had the items the following Tuesday! You can't beat that with a wooden spoon!!! Autoplicity HAS been bookmarked for future orders. They are the Crutchfield of auto parts!

Great Price!!<br>Fast Shipping!!<br>Would definitely use again....

Great deals at unbeatable prices!

Found a Thule Vertex bike hitch on here for $50 cheaper than amazon. Extremely fast shipping. Definitely recommend purchasing from here.

This was my first order with Autoplicity. I was pleasantly surprised when my order showed up quickly and was exactly what I wanted. I will be buying from this company again. Thanks for the quick service and fair pricing.

SO HAPPY! I have to admit, I was hesitant because I had never heard of autoplicity and there wasn't item a picture up for the Thule T2 rack I bought, but wow am I happy. Autopliicity had it for $100 less than other sites and the shipper was Amazon prime fast!!! Definitely a happy customer!!!!

I ordered a Thule 9002 Raceway Bike Carrier on Sunday, April 8 and received the product by Fedex on Wednesday, April 11 with just regular shipping. That is fast service. And the price was $43 cheaper than any other site on the internet (including shipping). I haven't had a chance to use the bike carrier yet but it appears to be new and as advertised with no issues as of this writing. I would definitely recommend this retailer for your next purchase.
