Great !

Quick and efficient

Easy to find the right part and place an order.

Very satisfied with the price and delivery time.

vert simple.

Autoplicity has great prices and quality products for sale, I'd give it 1/2 star less for slow shipping given the option. Took a while to get out their door, regardless, I would still purchase again, thanks Autoplicity!

Very good

Great prices, super fast shipping!

Had the parts I wanted and ordering through Amazon account made it easier.

2nd time using So easy to use and had the best prices available!!! A++++

Please send it in the Black color

After seeing that Autoplicity was in good standing with the BBB and had favourable reviews reported elsewhere I placed an order on a Sunday evening. On Monday morning I already had a confirmation email and order number. On Tuesday I was notified that my order had shipped. Their price of $477 on the part I ordered was about $30 cheaper than Summit Racing, who I usually do business with, and the cost of shipping and handling was only a few dollars more. I haven't recieved the part yet but have no reason to think I won't be totally satisfied with the transaction.
