I need a cargo solution.

When I sat in a Gen 3, it seemed quite roomy. Only after owning it for 3 weeks did it occur to me that the storage in the car is crappy. We previously owned a Gen 2, and the storage was much better. Does anyone have any storage solutions (such as extra cupholders/a comparable replacement for the storage area under the Gen 2's MFD)? Links aren't required, but are greatly appreciated. Thanks!
