FWIW, the vehicle I have had that had the most cargo room ever was an early-1980s Chevette hatchback (4-door with cargo hatch); when you flipped the back seats down, it had 6.5' long by 4' wide by 3' high. That's more than I have in my 4-Runner now. I don't know if any old vehicles like that still exist, but you would be able to get a bass into one; I used to carry *upholstered chairs* in mine. Or all my household goods, once upon a time.
