great price, hope shipping is not delayed

The product photo did not match item description for the year of Jeep Wrangler this item is for. Just want to double check when it is received that it is still correct.

Good price, fast delivery, just charge a little bit high on the shipping cost. Will refer friends to shop here.

Shopping was easy and being able to pay via Amazon is convenient. I do have to say autoplicity shipping emails and tracking webpage is behind. By the time they notified me that it shipped I had already received the products 2 days before. That's not a bad

Thank you! You were the cheapest and your service rocked! Got my item in less than a week.
