Hey Archangel, have you tried www.autotrader.com you can usually find the car your looking for on there. Don't worry about going from a V6 to a 4 cyl, the powerband will be allittle different but the 240sx has comparable torque and HP numbers to older V6's so thats no big deal. As for it being RWD just becareful in rain like dave said and be VERY careful when there is chances for ice, I have pirelli tires on the rear wheels and have had no problems in the rain. besides that there is nothing you can do when it gets bad outside.
And dave2nu, your so British it's funny <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> have you been to the 200sx forum it's a good forum on 200sx's.
