My friend made this quilt (she's got a VW Bug).

You could alter it to be a VW Van front image, or profile, using great fabrics:

Did you see the new van? Very cool.

You could do it via any method you're comfortable with - hand applique, machine applique, fusible (probably the easiest). And it's definitely within your skill set.
I think it would be fabulous.
