Great found everything I need

good

So far so good. First timer with this seller.

Picture was different then real product had to call to confirm fitment and was giving good answers.

Great company to do business with! Ordered a Thule 916XTR bike rack for my car and their prices blew away everyone else on the 'net! Ordered on Sunday, they shipped on Monday and sent me a tracking number that night. Super fast shipping and great communication! I'll definitely be coming back to Autoplicity again!

Awesome price on a B&W Gooseneck Hitch for my 2008 F-450 King Ranch

good

Great easy

Autoplicity is Awesome!!!!! I ordered a Aeromotive Stealth 340hp fuel pump for my 89 Supra Turbo. Not only did they have the best price on the part I ordered, the shipping was the fastest I've seen in a long time from any company. I ordered it on Wednesday, had it shipped to a freinds house where my car is and the part was there Friday morning. I was like DAMN!!!! That was fast I wasn't expecting it till Saturday or even Monday. Luckly my friend was off work that day so he could sign for it. With service like that I will definitely order from them again, even if the part cost a little more, cause I know I will get it ASAP!!!! On top of getting the awesome price, shipping, and customer service, now they are offering another $5.00 off my order. The only thing that could have been better is if they offer Military Discount which I forgot to ask about. Well kids the moral of the story is, that if you don't order from Autoplicity you are just plain DUMB!!!!!!

I ordered a Rhino stainless steel exhaust tip for my 2009 Chev Silverado from Autopicity. It took approximately 1 week from when I placed my order until I received it. It arrived in excellant shape and was exactly as indicated. The part was very good quality and easy to install. It took me approximately 15 minutes to install, partly because I wanted to make sure of the appearance and location. I was very pleased with the service I received from Autoplicity and would definitely order again from Autoplicity.

I had never heard of Autoplicity prior to this purchase, so I was a little hesitant to order from them. Man I am glad that I did!! Not only did they have the lowest price (by FAR) on the product I was looking for, but it showed up to my doorstep just TWO days after placing my order!! Autoplicity is awesome and will definitely be getting future business from me!!
