Ordered a H&R sway bar for my GTI from Autoplicity because they had the lowest price. I received excellent customer service and i had the part with in 3 business days. Can't beat them.

This is my second time ordering from Autoplicity and both times they had the lowest price on the items I was looking for (brake pads and CAI filter). Fast shipping, my filter was at my door two days later. Overall very satified.

so far so good

great site

Shipping was 5.00 on a 1.99 part but considering ebay was asking 18.00 for it I'm very happy

Autoplicity has the lowest prices. My new shocks were shipped within 24 hours with UPS Ground tracking#. Although I was expecting a closer warehouse than the San Diego one for my product to ship from (I'm in CT), I would still rate 8.5/10 stars.<br><br> The prices were so low that I ordered struts the next day so that I could take advantage of the MONROE rebate by ordering a full set. My MDX is sitting pretty and riding smooth once again. Thanks, Autoplicity.<br>order#8137 & #8177

Great experience.

Easy to use site.

Great price, fast shipping! Simply the best!

Autoplicity is my number one choice for auto parts.
