Well it actually has a role in the scene it's in - it doesn't stop for hitch-hiking bad guy Zigesfeld (in fact it swerves to avoid him) and he growls at it as it passes him.

But, 1 star or 2 stars, doesn't matter to me.

Here this Porsche is one star:

So too small I guess.

Couple more vehicles including the Porsche.

Porsche 928. 2 stars.

Mack-badged Renault truck. 2 stars.

1981 Ford Cargo. 2 stars.
