Difference Between Trims?

Hey, first post here :grinning:
I'm looking to replace my 1998 micra in around a month or two's time, i'm going for a 2003-4 micra but i can't seem to find certain information about the difference between the trims, i know they're is E, S, SE, SX and SVE are those is order of how many gadgets and what not you get ? i've tried looking at parkers review site for the information, but i'm getting conflicting messages, like the S + E aren't supposed to have Air con, yet on adverts for the cars people are saying they do, if someone could clear this up for me it would be great.
Thanks.

EDIT: Also could someone tell me what these cool things on the lights of this model are, I've never come across these on a k12 before ?

EDIT2: I do mean the spec of each model, not the colour of the fabric or dashboard incase some confusion was caused.
