not sure exactly what it stands for but dx is below the lx and the lx is below the ex. generally the ex has all power a wing (some don't have the wing) and a lot of them have either a sunroof or moon roof. it has to do with the package deal you're getting

They are basically trim lines. DX has the very basic standard equipment. LX has some of the convenience features that are added. EX has everything on it, top of the line.

they all mean the extras of the vehilce and the engine /gearbox tye

I see some right answers on here. The designations DO stand for trim variations and I'll put down all I know.DX = "D"elu"X"e - Minor equipment (radio, AC)LX = "L"u"X"ury - Standard or Moderate equipment (CD, Power)EX = "EX"ecutive - Suitable for Blue collar execs/management (Fully appointed, all power, leather,etc)Si = "S"port "I"njection (or Induction) so labeled by Honda cause Si models have the strongest VTEC engines available.SE = "S"pecial "E"dition - Trims offered with options not available on other models (upgraded rims, sound, nav, etc)SE = "S"port "E"dition - Versions with more sporty equipment. (bigger engine, larger diameter wheels, sport suspension, etc)SE-R = "S"port "E"dition "R"acing - Higher performance models with bigger engines, better tranny, sport suspension, and may lack luxuries)SEL = "S"pecial "E"dition "L"uxury - Addition equipment on top of the SE additions.LE = "L"uxury "E"dition - Models with upgrades over standard packagesS = "S"port - sports enhanced models.T = "T"urbo - Cars with factory turbochargersGT = "G"rand "T"ouring - Very sporty cars named and modeled after touring car races.SS = "S"uper "S"port - Cars that are purely about horsepower and performance.HO = "H"igh "O"utput, cars that have higher performance engines than GT models. (Often combined GT-H.O.)Many of the others are just names like Acura's line or the Scion lines. Numbers usually refer to vehicle versions like EVO V, EVO VI, etc.

too bad si stands for sport injected
