Warning

California Proposition 65

I ordered a headlight mount for a 2004 Cayenne. The mount looked similar to my old mount in your picture , but when I received the mount it has is the latest version of the part which has upgraded mounts. I now need to order the upgraded mounting hardware. One of your competitors has the breakdown of this assembly on their website so you know that you need the additional hardware when you purchase the parts.

Pretty convenient

I have no complaints. The website was easy to navigate and checkout was a breeze. Delivery time was about what I expected.

fast very good price and easy to work with web page

So far so good. I will wait for the items for more

WE COULD HAVE BOUGHT IT FROM THE SUPPLIER OURSELVES. WE CHOSE YOU, IT WOULD HAVE BEEN NICE IF YOU HAD IT ON HAND LIKE YOU INDICATED ... WE ENDED UP HAVING OUR CUSTOMER WAIT FOR AN ADDITIONAL WEEK.

Items names could be more specific

Good produced and fast shipping

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.<br><br>Best prices around.

Great service. Shipped out the day after I ordered it...plus it was the cheapest of the competition.

great

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Cheap prices, great quality, and fast delivery. Autoplicity will continue to receive my patronage.

Easy and fast. Order arrived very fast. Thanks.

Very smooth ordering and processing. Great communications.
