WHAT COLOR??????????help!

That GT Dart looks more like B5 than B3.

The fastback is B3 twisted with lots of micro flake
The Vert is B7 twisted with some microflake.

You can clearly see that the dart falls in between the colors.

Anything with a white interior will look awesome IMO.

Like they say, it's your car paint it whatever you like......except flat black :D
