Here is another example you could try, all in bash shell without external utilities or subshells except for the mv command, so it should be reasonably quick.

Code:
#!/bin/bash
oldIFS=$IFS
while IFS="," read -a car; do
  if [[ ${car[1]} != VIN ]]; then
    for file in *"${car[2]}_"*.jpg
    do
      if [ -f "$file" ]; then
        tofile=${car[1]}${file#*"${car[2]}"}
        echo mv -- "$file" "$tofile" 
        car[${#car[@]}]=$tofile
      fi
    done
  fi
  IFS=","
  printf "%s\n" "${car[*]}"
  IFS=$oldIFS
done < test.csv

It also does not entirely produce the proper output format:
Code:
mv -- 002795_001.jpg WDD1173461N6437866_001.jpg

, but it should give you some idea..

Remove the echo statement when it does what you want...

moon-buggy

moon-buggy(6)							   Games Manual 						     moon-buggy(6)

NAME

       moon-buggy - drive some car across the moon

SYNOPSIS

       moon-buggy [-hnsV] [--help] [--no-title] [--show-scores] [--version]

DESCRIPTION

       Moon-buggy  is  a simple character graphics game, where you drive some kind of car across the moon's surface.  Unfortunately there are dan-
       gerous craters there.  Fortunately your car can jump over them!

OPTIONS

       The program understands the following command line options.

       -h, --help
	      shows a short usage message.

       -m, --mesg
	      disable write access to your terminal by other users, so your boss can't disturb your game play with the help of	"write"  or  "fin-
	      ger".

       -n, --no-title
	      skips the title screen.

       -s, --show-scores
	      shows the current highscore list and exits.

       -V, --version
	      prints the program's version to standard output and exits.

KEYS

       The  moon-buggy	is  controlled	by  a couple of keys, which are described near the bottom of the screen.  Most important are the following
       keys.

       SPC, j makes your car jump.  The length of a jump is fixed and you can only start a new jump, while the wheels have contact to the ground.

       a, l   fires the mining laser.  The laser is used to remove stones, which may block your way.

       q      quits the game prematurely.  But you still keep your score and may enter the highscore list.

FILES

       The following files on your system are related to moon-buggy.

       /usr/games/moon-buggy
	      the moon-buggy executable.

       /var/games/moon-buggy/mbscore
	      the global score file

       $HOME/.mbscore
	      the local score file.  This is used, if moon-buggy has no write access to the global score file.
