Autoplicity had all the parts I needed to refurbish my Norcold refrigerator for a very good price. Shipping was fast and everything showed up in great condition and on time.

This was an awesome experience. I thought I was going to have to have 2 days of car work due to not ordering in time, but apparently what I needed, shipped from Commerce City (and I live in Colorado) and it showed up in 2 days during the busiest ship time of the year. Also was the cheapest price by quite a bit.

I tried to purchase a fuel tank from a competitor. They steered me to a part that looked like mine but was wrong.
When I found Autoplicity.com the site was easy to use and I was able to find the correct tank for my truck. The shipping was fast and best of all the price for my tank was the lowest I could find.

It was great, you had excellent prices, and the 2nd day shipping was better than most competitors.

I am extremely happy with my purchase from autoplicity. I received the best price on the web and was given the convenience of paying through amazon. Very fast from order to delivery.

competitive prices and good selection. Will definitely look to this vendor when purchasing automotive parts in the future. I ordered a roof rack and it was very hard to find elsewhere and the few places I did find it, it was more expensive.. it was cheap and easy here. thanks :)

Couldn't be more happy with my product. I ordered from Autoplicity because they were the cheapest price around and I received my order within 5 days. I have installed the cold air intake and couldn't believe all the extra power. I am very pleased with the entire transaction.
