The skinny girl's standing outside the van cause she's a prude. Her chubby friend, who likes to have fun, is in the back on the left hand side which is why the left wheel has the tilt.

On a less sexist note though, it's amazing how cheap an interior looks with a wood rimmed steering wheel. You can't improve on the factory GTS wheel, and it's a must have if you're going to ask $40k for a plumbers van.
