I tried to place two orders and it automatically did three. Lol.

quick

After searching site for a solid hour (which supposedly caters to Audi enthusiasts) looking for the part I needed, ten seconds after entering my search terms, I found the exact part I was looking for on Autoplicity, at a price less than half what the other site wanted, including shipping. To be sure I was comparing the same part, I searched using the Audi part number Dorman provided, and found the exact same part, priced nearly 100 dollars higher. In future I will look to Autoplicity first, and pass the word to my German car enthusiast friends.

so far so good

looks ok

Very friendly customer service! They also shipped my radiator out very quickly. I will definetly be ordering from autoplicity again!

i like what ive been reading on the reviews
