In any case, there are so many things that would make Forza 3 192831092831 times better.
A.) More paint options. We need pearl, and flat, and all that good stuff. Also the ability to paint other things. Not being able to paint a wheel because it is stock is silly, not being able to paint it because it is chrome is silly. Also, the ability to paint things like grills or such would be nice. I wanted to make a G8 Firehawk Replica. The grills aren't chromed on the Firehawk, and you can't have flat paints anyway.
B.) Also kind of a paint this is, the fact that if you have a car with a design (like the 2010 Vette GS's Fender Stripes, the Firebirds hood paint, or the 90 Camaro IROC-Z's stripe), and you either choose a color, or not to have it at all, you can't go back. If you chose red, it's red, forever. If you chose not to have one, you never will. If you chose to have one, you can only cover it up with vinyls.
C.) Certain oddities could be fixed. The Solstice I know for a fact has an aftermarket bumper that has a dual-exhaust outlet, but otherwise looks the same... if you buy it, you still have single-exhaust and an empty hole on the other side. Upgrade exhaust doesn't fix it either. Also, tuning cars and lowering the adjustable springs, or even raising them, doesn't show a visual difference, which in my opinion looks silly.
Just thought I'd vent that, I'm sure there are some other things I forgot, or other things other people would like.
Also, WTF NO GRAND PRIX GUIZ
