Hi, Some time ago I have imported elevation contour lines into Autocad from GRASS using the module "v.out.dxf" which generates a DXF file (readable by Autocad). It worked quite well except that I had to add the elevation value as a contour line parameter in the DXF file. You need this if you want to get the z-Value (elevation) when clicking on a contour line in an Autocad worksheet. For this feature a break up the source code of v.out.dxf but it was no big deal.

That's a cool idea using a R/C truck but is the relative/absolute accuracy sufficient for your needs? Do you want to use GPS or differential GPS? For high resolution digital elevation models (1-3 m horiz. res.) you can use stereo satellite images Quickbird/IKONOS or even stereo oblique photographs? But this maybe also a question of money :-).
