I'm tired of my melons rolling around the back of my 2015 Volt. The rear of the car has three sets of devices to which accessories can be attached. the first is a set of four little pegs near the top of the cargo area. These are for what i call the tonneau cover, which Chevy supplied. the second is a pair of protruding bolts on either side of the cargo area, on either side, near the top. these appear to be for a kind of long net basket which mounts vertically, and which Chevy did not supply; i looked for this because when i bought my Prii, Toyota supplied them. Third is a set of four rings near the floor of the cargo area, at its corners, for holding a horizontal cargo net. Again, i'm familiar with their purpose because the net is standard on the Prius. Chevy says that one (i'm not sure which one) of the second two devices is available, but my dealer cannot find it in his parts list. And, they have gottten so tired of hearing me complain about this and an egregious bluetooth problem that they have given me a $250.00 accessories credit to shut me up. So, all of you... how do you keep your melons from rolling around? And, what other accessories would you suggest that i might get with my $250.00 credit? It's a one-shot offer. I understand that some of you will think i should just buy another Prius, but I like the Volt. I'll just like it better when my melons stay put. Thanks!
