small penis car 

Also applies to humongous "manly" vehicles that are not allowed to wear dirt, let alone get driven on it. Glossy Hummers, pinstriped pickups, and similar macho-but-impractical trucks and SUVs that cruise cities and suburbs.

The Hummer is the most useless vehicle ever built; it's the ultimate small penis car.
