I've only owned two chassis, B13(NX), and B15 SE-R. I've driven my mom's old P10 many times, and I liked it. Never been in a P11, or B14. Never touched a classic either. Though I like to. I see it like this, B13(NX), P10, B13(classic), B15, P11, B14. The last 2 are based on looks alone. I don't care for either much, but never drove, or ridden in.
