Order 12486. Item was simple to find and the website made it very easy to navigate. I appreciated the ability to pay with paypal and email notifications gave me confidence that everything was taken care of properly.

shipment came on time, and was nicely wrapped.

Just received my order! I placed the order Sunday night and received it on Tuesday, super fast shipping! The SS vent caps look great and arrived in perfect condition. Thanks!

Very nice people very considerate and helpful plus the price was nice

I placed the order on Monday, and the package was delivered two days later, on Wednesday...and that was with FREE SHIPPING!!! It was also at the best price I could find. What more can you ask?

Very quick and easy. And the price is the lowest I've found. Juse wish it would have stated somewhere that you still have to have the keys reprogrammed.

Return customer with a few more future purchases in mind...best price plus quick shipping means these guys are just that good!

Very smooth ordering and processing. Great communications.
