Brother, they only Big thing or Edge that i consider of a GLI is on XLI is its color option.
I would like you to go for a metallic color as its Graceful.... I have a Gun Metallic color Vitz. I like its color alot... I would like you also to buy a Metallic Sober color.
I have chosen Following colors from its Site:
1st choice= Medium Silver,
2nd choice= Silver.
I will be going for XLI because there is no Engine change and hopefully in Black color which will look complately matching.
BEST OF LUCK.
