I ordered from Autoplicity because they had the lowest price for an exhaust i was looking for. I was kind of iffy at first but then i read all the great reviews. Very fast shipping and delivery! I will be coming back for my next auto needs. Thank you autoplicity for your great prices and customer service!

I am pleased with Autoplicity. There was a miscommunication on shipment, but after a phone call, everything was handled. Looking forward to my parts coming in. Thanks guys!

I purchased an Optima Red Top 75 battery from Autoplicity and they have some of the best prices available.  The item was shipped right away and they knew the inventory that was available, not like others who said there may be a 2 to 3 week shipping time frame.  So far the service has been great and I look forward to continued great service.
