To make the program pause at each five lines we will have to count the lines. The i variable in line 4 will hold the counter.

   1:cars_file = open('2006_FE_Guide_14-Nov-2005_download.csv', 'rb')
   2:
   3:# i will be our line counter so we know when to pause
   4:i = 0
   5:
   6:print
   7:
   8:for line in cars_file:
   9:
  10:    i = i + 1      # increment i by 1 at each line
  11:
  12:    print line
  13:
  14:    if i == 5:    # change 5 to whatever you think is adequate
  15:
  16:        i = 0      # zero the counter
  17:        print
  18:        raw_input("Hit Enter to continue: ") # wait for the user
  19:        print
  20:
  21:print
  22:cars_file.close()
  23:

At each line read from file the counter is incremented by 1 (line 10) and when it gets to 5 it is reset to 0 (line 16), so it can count to 5 again, and the program asks for user input.

The list is too long and if you want to stop hit Ctrl-C

The values in each line are intentionally separated by commas (.csv file) to make it easy for a programmer to catch each value. We will do it next.
