prismacolors are awsome ,they lay down so smooth compared to other pencils which is perfect for cars,but because of this they break real easy and go blunt really fast but i do have a heavy hand
polychromas -are great aswell,they last longer lay down well but not aswell as prisma
and of course theres derwents aswell they are my prefered 3 in order i guess,
maybe for now buy them as singles fro man art shop supplier and try them out for yourself and whichever brand you prefer then buy them as a set
