I love them both, but I own an S14.
The car that originally turned my head though was an S13 back in '94. Bye the time I was able to buy a new 240sx in '97 they had changed the style so it ended up being an S14 since that was the model for that year <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>
