Nice article - that's some good research!
The one-make Mirage/Attrage racing video is particularly excellent!
Don't forget, the North American spec Mirages are the heaviest of the lot. If I'm not mistaken, the base '14's in Indonesia were around 1800 lbs. Haven't checked what the '18's are up to.
I'm certain this hatch is probably under 1,700 lbs. if not quite a bit less (since a factory version weighs just over 2,000 lbs.).
