Great price for the item. Both internet and phone conversations were quick and knowledgeable.

simple and quick transaction. thx

The engine oil dipstick was the wrong one for my car. Perhaps their automotive model database needs to be updated.

It was okay. Product doesn't completely look brand new, but I hope it does the job.

Ordered an Fabtech steering box skidplate, best price I could find on the net was Autoplicity. Price was better than all the 4x4 sites I checked. Item is shipping directly from Mfg, so really can't comment on shipping speed. Otherwise, transaction was easy and I really like the fact they accept PayPal.

Was for head gaskets. They used to come 2 to a pack--now same price and there is only one in the pack (1135g) Mr. Gasket. Knowing this, I wouldn't have ordered.

Good transaction, no problems, fast ship, quality product. Thanks

Great pricing and great customer service. They took their time with me and made sure what I was buying was the right part for my truck. Thanks and will purchase from you again

It is awesome that you guys can get this part! Half the cost of competitor. As long as shipping goes well, I will definately be shopping here more often!!!

After a almost 2 month backorder through Summit... y'all had what I needed in stock and shipped same day! Which was delivered in 3 days! Awesome!

Please send it in the Black color

Quick and easy

The best pricing around and great shipping and communication when I reached out to them. Thank you Autoplicity!

Always great prices, fast shipping and great communication. Will order again from Autoplicity. Order#17421.
