You need to be concentrating on Learning Perl, as this code will not teach you all the parts you need to understand the whole. But here goes. All i did was grab the Synopsis code from the documention for Spreadsheet::ParseExcel::Simple and added a line to open the output file and line to print each row of data from the spreadsheet (seperated by a single space) to that output file. Since you didn't specify the column numbers for vin, model, and year ... well ... i'll just make them up! This code is untested:

use strict;
use warnings;

my $xls = Spreadsheet::ParseExcel::Simple->read('/tmp/carlist.xls');
open OUT, '>', 'carlist.txt' or die $!;

# these are made up: vin = 2, model = 4, year = 7
# put the right column numbers in here
my @cols = (2,4,7);

foreach my $sheet ($xls->sheets) {
   while ($sheet->has_data) {  
      my @data = $sheet->next_row;
      print OUT, "@data[@cols]\n";
   }
}
