Good order experience although I received one confusing email from Autoplicity and had to call them to get it straight. Shipping was a little slower than I would have liked.

Smooth

Order for Borla exhaust filled quickly, correctly and shipped safely. Previously I had to cancel an order for the same item at a competitor who gave nothing but excuses for non-shipment of item. And at a higher price! Autoplicity had best price, service, and followthru on purchase. Will be a returning customer without a doubt.

Smooth and easy transaction!!!!

So far so good no problems encountered

I bought a bicycle rack. It seemed like the product was delivered before I had even known it was shipped. Great price!

Fast shipping! Good prices! Will recommend to others
