The quality of the caps is really good, they are not plastic but the Corvette logo is a C7 logo not a C6 logo. In the pictures they are advertised as C6 valve covers but the ones I received were for the C7 Corvette. I won't be returning them as I don't mind too much, plus they were cheap but for anyone interested, don't buy them for your C6 as you will get C7 style valve covers instead.
