So far so good...Hopefully its truly a MASTER Lock! Thanks.

The website has been having problems. I have tried to sobmit an order about 3x, and either the website gets stalled with the blue steering wheel turning back and forth, or getting stuck on not providing the 'State' pull-down, or something. I finally got

Easy site to manage

Easy check out with Amazon

Fast and hassle free! The one down side was the Hurst Shifter came without the shifter ball even though the picture showed it with the ball.

They have great prices! The same item I purchased from autoplicity is on summit racing for triple the price! This is my first order and I am very happy, will order from again!

thank you

Quick and easy. Hope they have shoes in stock.

Autoplicity has an abundance of name brand parts at unbeatable prices. Customer service was also great to deal with. Receipt and tracking info was provided promptly.

great

Totally impressed with the headlights. Took 30 minutes to install with a perfect fit. Amazed that they even came with light bulbs pre-installed. Keep up the good work. Now I have to check for 5" round halo lights for my wife's 1987 Jaguar.

I was a bit concerned buying from a online retailer I had not done business with before, but Autoplicity is now on my list of preferred vendors. I was sure there would be some problem, as the part I ordered was $73 cheaper than anywhere else online (too good to be true). Well, the part arrived super fast, and was exactly as I ordered. I did not hear from them immediately after ordering, but received confirmation and tracking info when the item shipped, which was two days after ordering. All in all, a great, money saving experience.<br><br>Update:<br>While I am still pleased with the service I received, I find it odd that Autoplicity emailed me and offered me a refund of $5 for writing a review. It has been a couple of weeks since I posted my review, and I have yet to see any credits on my credit card.
