    We are redoing our 2002 GMC truck & was able to order the necessary part. In error, with a computer issue, 2 parts were ordered. A quick email to the vendor explaining what happened & that we only needed 1 item, our account was credited. Very prompt service, fast shipping, quality packaging, and attention to detail. Very responsive to our order. Thank you!

    It's was shipped in a timely manner , the box was beat up a bit but I expected that from how far away it was being shipped from . Part was in great condition because it was packaged well and appeared like new . I chose Cardone because of their quality and value to have part shipped to your door . I haven't installed parts yet but will soon . Overall great service exceeding my expectations , thank you .
