Anxious to try your product

Easy ordering

I bought 2 pairs of Stainless Steel polished 12x16 mud flaps. I looked at quite a few mud flaps for my Escalade EXT, and these were the only ones I could find that were not plastic or rubber. They are excellent, heavy duty, polished stainless flaps; and mounting hardware was included. They were well packed, shipped fast and at a very reasonable amount. Best of all they were $26.00 cheaper a pair. So I saved $52.00, got fast delivery, and got a very nice product.....Thank you Autoplicity; definitely saved in my favorites....Bill in Pittsburgh, Pa.

Great prices and super fast shipping. Good job.

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!!!!!!

Product was a good price, fast shipping and great costumer service! will do business again!
