Regarding the scale problem with minifigs: it's hard to see a lego dude as anything like a real person so I just like to suspend scale criticism, nice mini van though. Here is another I did of the Mustang. This is the first gen, it looks right from the top and in proportion, but i've been having problems with the scale along the side profile I can't get the wheels half a square across so they seem too close or too far apart. I'm currently shortening it but it looks too square and proportionally its now the same size as the 8 wide ferrari. It's built off the base of a 8 wide skyline so that driver is co pilot. Next i'm going to try the Ferrari FXX K from a couple of years ago, it was, in my opinion one of the worst cars, it looked very little like the original concept.
