So I'm trying to figure out what the interior differences are when you put the Night Edition package on top of the GT. It's a $2k+ package and I see that most of the additions are for outside parts, ie: badges, wheels etc. But it states that the seats are leather trimmed in the Night Edition package vs. Leather/Vinyl seats on the GT package alone. Is it a big difference? The configurator breaks on me so I can't really tell what it looks like, but also those pictures aren't very clear. Is the reason for the Night Edition package so you can option red leather interior with the GT package? Confused.
