When I moved here with my brother I had the following in Mean Green:
Kitchen table + four chairs (Back seat, dissasembled)
Coffee Table (Trunk)
25" TV (Pass. seat)
VCR, DVD, Dreamcast, Playstation, Saturn, Virtual Boy, SNES, NES (Pass. footwell)
Two air matresses (Pass. footwell)
TV stand, Stereo stand, speaker stand, book case (Back seat, disassembled)
Night table (back seat)
All my clothes (Trunk)
Enough food for the 1st week (Trunk)
Microwave (trunk)
3 cubic foot sub box for the PB15 (duh, trunk)
I think I was overloaded though, I had to leave the back windows open so the chair legs wouldn't break the glass if I hit a bump.

My brother was right behind me in the Jetta with:
Desk chair
Desk
All the cooking and cleaning utensils
13" TV
Night table
5' tall book case
two fairly large chairs for the living room
All his clothes
We moved 80% of our stuff in one trip using two cars. Well planned, you can fit anything in a car... except a damn couch... 1.5 years later I still haven't moved my couch here
