My brother bought spoiler from the company www.corvettemods.com. The cars have never been my strong point, so I asked my brother to help. When he saw the spoiler, he told me that I could throw it away, because it was useless and the company has fooled me. Also, he advised me to speak with the seller and to get money from this guy. But the seller spoke in rude way with me and it was so unpleasant. Beware that such problems can appear.
