Great website

Great

Fast action

Very easy to use, free shipping, A+

Good this far.

I just got it. Not sure about the rest. Thank you

So far so good

I have a MerCruiser 5.0 please make sure the proper cables are in this order

I haven't received my parts yet, but they just notified me that the order has been shipped. I think this is very fast service. Their online ordering system was very easy to use. And best of all, they had the lowest prices on the items I ordered. Even the shipping charge was less than some other companies. So far, I am very satisfied with Autoplicity, and I will certainly check their Website the next time I'm looking for parts.

Ordered on a Friday and they had it shipped by Monday and will be at my door step by Wednesday. Prices are amazing I will have to buy from them again.

Best prices, fast shipping, and product as described. I would definitely recommend Autoplicity.

Good

Great products. Super fast shipping,and best prices anywhere! Thx!!

Fast, Professional and great prices.

GREAT PRICES FAST SHIPPING WILL UPDATE ONCE PRODUCT ARRIVES

I enjoyed the quick and simple the checkout process

Autoplicity has really good service. They give you such good prices and yet they're still willing to give you discounts on your purchases. They emailed me a day later after purchase with shipping number. I would recommend them to anyone!
