Like it thanks

Fantastic! Will definitely do business in future!

Overall, good service! Thanks!

Works great

Site was a bit confusion making sure the parts I ordered would fit my vehicle. I understand some parts are widely used across but for the Challenger Hellcat I know for a fact that the brake pads for it and the other challenger lines are not the same. So worried about the rotors as well - we will see when they arrive.

First time user, went smooth without any issues. And lowest price

Awesome place to buy goods. I wasn't able to find the item I bought cheaper anywhere else. I will definitely buy from autoplicity again.

so for so good
