Excellent prices + great customer service = people I want to do business with... period.

Awesome price! Shipping could be faster, but it was fast enough. Will deff buy again.

Good customer service.Very friendly persons in service dept as well. Will shop here again.

This is the first time I've ordered from this site, but things look good from what I can tell so far. They had the parts I was looking for (including a fairly specialized racing part) for a price slightly lower than other places I had looked, and my order shipped the next business day. At the time I wrote this, they were also offering $5 back on my order for writing a review. ;-)

So far I am happy with Autoplicity's order status updates. I like when shipments are in process and with the updates I know progress is happening. When an order doesn't seem to be moving along a customer wonders what the hold up is. Well so far I don't have to wonder which makes me more patient in waiting for my order. Thank you, I will explore Autoplicity's website for more cool stuff for my car.

very good low price, had a slight issue but customer service was amazing,. i would recommend AutoPlicity to anyone because of that, good prices, good customer service,. (meaning trust worthy) why not :). A+++ Service will buy from again!
