My thoughts are:

1. The console should be located forward enough to still allow someone in
the passenger seat to step between the seats and get into the back while
traveling.

2. Cup holders a must, but should be somehow variable in size and deep
enough to fit both the smaller cans...and also hold larger water bottles
without falling over. One aftermarket plastic console I have has a sliding
piece that accomodated different cup/bottle sizes...rather than just a hole.

3.  Two extra twelve volt outlets please.

4.  A bin for sunglasses with a lid.

5.  A bin for a CD changer, also with a lid.

6.  A "dished bin" for change...or one of those little sized change holders.

7.  A thin pocket for maps...easy to get to.

8.  I liked the subwoofer idea...if there's room.

9   Perhaps a place for a non-critical gauge or two...like a voltmeter for
the auxiliary battery. I'll keep my engine gauges on top of the instrument
cover.
