hehe, nice thread.
now beside the already suggested minivan (last year chrysler/dodge had a brand new dodge caravan AVP a more "base-model" for around 17-19k + title+registration+dealer fees)
-ford freestyle (if CVT transmission doesn't hit you with the 4k-7k repair/replacement)
-ford taurus X
-ford taurus wagon (fleet-use/maintained 2001-2004)
-ford focus wagon(2005-2007)
-ford transit (they could "eat" a whole pallet)
-dodge magnum (the wagon, not the truck)
-mazda5
-chevy hhr
-if diesel: jetta wagon diesel or passat diesel (with the even rarer stickshift and large gas reservoir conversion you could get 1,000+ miles per diesel tank); good diesel and vw mechanics in the close area mandatory!
-the old pre '95 honda accord and toyota camry wagons.
-scion xB (2008 and up)
-older volvos wagons (240/840)
-(and based on the AWD vans) astro chevy conversion van... with captain chairs
-and of course the old wood panel/8 seater/could fit 4x8 drywal sheets in the back/"your-granpas-chevy-chase-family-vacation-wagon"
yes, i'm kind of onto wagons, but it's basically a car/truck with a roof....
