    I’m sure you ( the seller is Rancho Cordova Auto Parts) was good. But, I got problem with the package, you send the package by UPS. Unfortunately, the UPS delivery guy, just leaved it the package OUTSIDE THE APARTMENT BUILDING. I don’t know, why they did that. It was uncorrected did. The UPS delivery manager, please responsibility with yours guy did. Thanks everyone to read my message.

    Exactly as is described. Worked great for my 2006 S40 Volvo. The item arrived quickly and was wrapped extremely well. I would recommend this seller. Very good experience. Great price for this item as well.
