Cheapest priced ARP head studs on the internet. A++ I will definitely do more business with Autoplicity.

Merchant agreed to resolve the issues. Items were received after 3 days and received the lowest price.

Processed and shipped fast. I was a little upset with them shipping my Eibach springs in the Eibach box, and not repackaging it. Everyone could see the box, and knew what was in it. But this will not stop me from ordering again.

Found what I needed at an unbeatable price, easy purchase! No issues

The correct product that I ordered, and easy to find through there web site.thanks

Glad I found Autoplicity.com. Big potential...<br><br>Ordered parts on Friday, missed 1st delivery attempt to office yesterday (Weds), but received today (Thurs). Little slow on the shipping, but not in a rush for these parts. We typically receive UPS pkgs in 1-2 bus days from Chicago suburbs to Metro Detroit. This took a bit longer, but again - it was not a problem & well worth the savings.<br> <br>Wish web-site would actually separate items for just my car vs all vehicle matches. Finding what I wanted was very difficult, but I'm very pleased with pricing & follow through. I've been back on Autoplicity 2 times now looking for add'tl parts for another vehicle, but have yet to locate them amongst the 100's - even 1000's of results that do not match. If finding them were easier & these add'tl items offer similar savings, I would have spent hundreds more by now. <br><br>If this is a new company, hopefully they can correct the advanced search option as well. Entering a part by vendor name should net results when the brand is listed on the home page & can be found in general queries. Even when I entered the part # for an item it shows no results, but again - searching several dozen pages, I am able to find the same part #. The savings were worth the headache it took to find the brake pads for my BMW, so I won't give up just yet. <br><br>Thanks Autoplicity! Here's to a potentially great future!!
