i know it's not the most 'manly' thing to drive, but i'll use it for my commute to work and back (i live only 3.5 miles from where i work). that'll definitely soak up some savings in gas - $60-$70 every other week from my gas-guzzling premium-drinking Z.
this is what i wanted, but the wife said no. someday...
