Well, part of the customization process of the C6 we got was to doll up the interior. The coupe makes the back cargo area seem very large, and this is a problem if you don't want something you set back there being flung towards the back of you tromp the go pedal with meaning. So I looked around and found someone selling such a partition (Exotic Vette out of Orlando) and ordered one. Supposedly this is one of the few that will allow you to utilize the storage area for your top, whereas some will not.
Anyway, went in in about 10 seconds and certainly does the job..
Also noticed the Lloyds rear cargo mat that I got around the same time. Got them front and rear and they are WELL worth the money.
Oh yeah, got an aftermarket cargo shade as well. This is a REALLY nicely made item. And the logo looks pretty sharp!
