RS, base, but most options available. comes with 3 gauges not available in any other model (maybe some AXIS?)
RX, 6 stacker, electric seats, rear seating aircon vents. no Hicas option, therefore no LSD.
ARX, fully optioned, same as RX but with; leather, TV/satnav, hicas, LSD, extra 40mm heigh, ugly ass side moulds
AXIS, lowered suspension, body coloured side moulds. most options available.
