The Astons are curvier, have better proportions and the rooflines don't end as abruptly as the Xfire's. The roofline in the Astons have a nice gradual declination that terminates nicely into the rear. The Xfire's line drops abruptly downwards. The overall look of the Astons are much more elegant and sexy than Xfire's. You can't really deny what the above pictures spell out. Please, Don't Take This The Wrong Way!!!!!

Don't get me wrong ... I'm not saying they are twins, more like cousins. I look at the 2 cars & see how some of the lines in the Vanquish could have INSPIRED some of the lines in the Crossfire.
