Well I think the main visual difference is that simply L has orangd colour speedometer & X G has blue.
L has only headlights adjustment switch & idle stop button. Rims are on L limited.
On other hand
X has both the above with traction control button and some more features. Rims also on X limited.
G top of the line has auto control Ac,push start,rims, stability assist , traction control maybe some more.
Also pre collision system comes in limited options.
