Add 50k more to the market price of simple 2007 Vxri in similar condition to get an idea of the price of 2007 vxli.
750 looks a little steep for a 2007 cultus vxl or not vxl. Once you get it at this price and after a touch up or repaint it will loose alot of its value at the time you decide to resell it. No body will pay more than 650k.
I sold my VXL for 400k last year but it was 2003 model and 50% repainted.
