Dear Liz K.,
That's a good question, but unfortunately, we do not have an answer on it. It is better to ask the SiteJabber support to explain how the rating calculates.
To answer your question about why you should buy from us, I would say that we have a huge variety of the OE replacement and aftermarket automotive goods and if you are fixing or restoring your vehicle you must look through our website. We do guarantee the lowest price and good quality.
If you have any questions or concerns, please give us a call at 800-505-3274. We will gladly assist you.
