Extremely Happy! Best price on the web, easy order tracking, if only all online orders from other sources were this easy. I ordered a component from another online retailer who showed parts "in stock" only to see my status as "sent to warehouse" and it was weeks. When Autoplicity shows "in stock" it really was and delivered right away.

Buying was fine. Let's wait to see about fulfilling, shipping, and quality of order.

Simple ordering process, and the product was exactly as advertised.

Fast service and the cheapest price on the web. My item arrived on time and in good shape. Order Number: 11517<br>

good

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.

No immediate info as to if this is in stock and will arrive in 2 days as I paid the addtl34.

Best prices, fast shipping, and product as described. I would definitely recommend Autoplicity.

good price
