    The quality of the item was simply perfect! It provided and instant upgrade to the interior of my SUV the condition was excellent, the appearance was exactly as described and it was a great value! The seller was also very responsive and kept me up to date on the process and I actually received it several days before I was expecting it which really made my day! I highly recommend this seller and will continue to look out for other items that he might be selling.
