yuh make me went n dig up for this info eh! LN130 specific not sure if same applies for LN61 and KZN's!
SSR-Limited - fully loaded 2L and 3L engine options,sunroof, same general interior as other LN130's (except some with 2tone interior), chrome badge on steering, clinometer gauges on passenger side,alloys,full brush bar,rear spoiler with brake light,hood rails,aluminum side step,adjustable shocks.
SSR-X - loaded, sunroof as option, regular interior,brush bar standard alloys,aluminum side steps,adjustable shocks. 2L and 3L engines options.
SSR-X wide - fully loaded like the limited, more body cladding, wider fender flares, 9.5" or 10" (not too sure) wide alloys, larger sunroof. 3L and 3VZ(gas) engines,adjustable shocks. [Note there is also an SSR-X wide without all the fancy stuff only the wider flares and brush bar)
SSR-G - basic powered features, 2L engines and 3VZ, 2 tone interior in 3VZ, mini brush bar as option, basic alloys.optional sunroof and rear plastic spoiler,side steps.
SSR-G wide - same as SSR-G with wider flares, 9.5" wide 16" wheels, rear plastic spoiler (no brake light),mini brush bar,side steps.
SSR-V - same as SSR-X with wide wheels, (no wide flares),alloy wheels, 2 tone interior, 3L and 2L engines,adjustable shocks.
I may have missed out some features, but that's the general gist of it. In addition this is some options available from the dealer when they were new:
Window visors,aluminum front under shield, JAOS,AIRA or TOYOTA badged brush bar,side steps,fog lights on brush bar,roof rails, rear spoiler (with and without stop lamp),16" wheels (9.5" wide),rubber step on rear bumper, rear ladder,tinted glass (dark glass), chrome handles and side mirrors, rear blower(in winter package models),dual batteries (in winter package models).
Ugly red interior comes in the LN61 SSR-limited,SSR-x wide and SSR-G wide. and some LN130's in SSR-X wide, SSR limited.
