Reasonable price and shipping Wrong part!

A+

Will see when I receive my parts that I ordered how good. Some of parts that I received are not same as pictured and ordered.

Wouldn't take first debit card applied.

So far so good. Will comment more after I receive my goods.

The site was very easy to shop and the prices are great compared to other sites. The item arrived much faster than expected. The only picture of the product on the website was not the actual product and was something totally different but the item description and the information requested (make, year, model etc.) assured me it was the correct item. Overall 100% satisfied.

Easy!

Quick and easy thanks!
