I don't think you can do that directly with sh, however you can have those
values assigned as positional parameters, eg (assuming return_car_values.pl
returns "model1 red 2005")

ret=`return_car_values.pl`

eval set -- "$ret"

# now $1, $2 and $3 are set to "model1", "red" and "2005" respectively

All the commands are tested with bash and GNU tools, so they may use
nonstandard features. I try to mention when something is nonstandard (if
I'm aware of that), but I may miss something. Corrections are welcome.
