Super fast shipping

Easy and accurate

.

A+ parts, price and service. Top notch!

I have tried calling three times to order a boat propeller. All three times, the woman answering the phone could not understand me. After the 3rd time of spelling my name and email address on the final call I gave up and hung up on her. I apologize to you for hanging up on your staff. Your site seems to be very nice and the reviews are excellent. I hope that the delivery service you have is just as good as the reviews. I had preferred to order by phone because I'm not a fan of internet ordering. The photo shows a hub kit with the propeller. There is nothing i could find noting that. I assume that comes with the propeller. Thank you so much....... Nope no hub kit like the one pictured with it... Fortunately the hub off my old prop matches. Delivery time was awesome! Less than 4 days.

Faster shipping than I expected. Easy order process. The ignition switch was my problem and Autoplicity part was exactly what I needed at a price better than anyone else had, with shipping included. I will definitely look to them again when I need any more parts for my Monte Carlo SS.<br>Only slight negative would be it took a few days to get an email with tracking number so I would know when my part would come. But once I got it, found it was coming sooner than I originally thought, which was great.

Great price and fast shipping. Good experience!

good price

Very fast shipping, the product should arrive today acording to UPS, and I order it 2 days ago. The customer service is also great.<br><br>Thanks again,

The shipping was fast and the customer service was great. I accidentally hit submit twice, and they promptly cancelled my accidental order. If you have any problems, just call!

Very fast shipping and bottom line prices for every part. Awesome website. Will be telling all my friends about and using again for sure!!

So I have an old car. It's and 83, seven years older than me. I'm also a student so I don't have much money and need to make as many repairs myself to save money. I go out to the local pep boys and auto zone to to try to find a repair manual that is for my old model but it's not available. I check online and there are very few copies on line. Autoplicity had the right manual at the lowest price by a good margin. <br><br>TLDR; Autoplicity has EVERYTHING and at a cheaper price

Prompt order processing and shipping, the item I received came in good condition and I am eager to get it installed on my car. Over the phone customer support was prompt and polite, I would order from them again.

The magnaflow kit that I ordered was about $100 cheaper than any other site I could find. Shipping was fast, and relatively cheap too.
