I was looking for a part for my Mallory distributor at a fair price. I called around to my local speed shops and they all had to order the part, so I went on line. With a little research for the best price here, at Autoplicity. I ordered the part last night and it has shipped 24 hours later. I like that. I have bookmarked Autoplicity so I can use the again. Thanks guys.<br><br>Jim

Have not recieved order yet, but price was good. Will see how long it takes and if I get the right product. Writing this review before arrivial.

Had problems using the search tool so I called direct. They helped locate Air Lift shocks I needed and told me that I.E. browser is sometimes a problem. They were helpful and my items got shipped the next business day.

Had the best pricing for the item I wanted and customer service was excellent. Called about shipping and were responsive and quick to get me the details. Will buy from them again.

My order for a "Thule" bike rack went thru like silk. Was received (1) day early. Would recommend "Autoplicity" to anyone. Best buy I could find on line.<br><br>Customer in Kokomo, IN

Autoplicity was a great place to shop. By far the lowest price on the rack that I purchased. Fast shipping and overall very satisfied.<br><br>

Excellent and very quick service. I could not find this product in stock from any other supplier so I kept hunting. I found Autoplicity and from now on they are the first company I will try. Thank you.
