Why use any kind of awk; cut will do the job.
But whichever utility you use, the principle is the same: set the
field delimiter to a hyphen and print the second field:
awk 'BEGIN { FS = "-" } {print $2}' car_models ## or gawk or nawk
Or:
cut -d- -f2 car_models
Or:
while IFS=- read a price
do
echo "$price"
done < car_models
Or (a little differently, delete everything up to and including
the hyphen):
sed 's/.*-//' car_models
