Everything was great!

A+

Didn’t know you all existed!! By far lowest priced AND free shipping!!!!

I highly recommend this DC Sport strut bar. It was very easy to install, looks pretty cool, and you can't beat the price. Also I noticed a difference in steering as soon as I started driving around. All in all awesome product!

Fabulicious!

Had tires that were hard to find for my car and shipped them out same day!

All worked out well. Happy with the product.

Was easy to find what I need and for a great price!

Easy purchase and checkout.

great prices, fair shipping price.

Product was as described, shipping was fast, and communication was excellent. Plus I saved $$. Thanks Autoplicity! I'll be a repeat buyer and referral source.

So far so good

After seeing that Autoplicity was in good standing with the BBB and had favourable reviews reported elsewhere I placed an order on a Sunday evening. On Monday morning I already had a confirmation email and order number. On Tuesday I was notified that my order had shipped. Their price of $477 on the part I ordered was about $30 cheaper than Summit Racing, who I usually do business with, and the cost of shipping and handling was only a few dollars more. I haven't recieved the part yet but have no reason to think I won't be totally satisfied with the transaction.
