Dude, no offence but when posting a new thread make sure your caps lock is off, im sure you'll get more replies that way. Coming to your question, ironically the XLi has more resale than the GLi although the XLi doesnt have any power windows, power side view mirrors or metallic colours. That aside, there isnt any great difference between them, but the XLi will fetch you a few grand more than the GLi. No real difference.
