Volkswagen Beetle

"Sam, something's wrong with this old car. It's making strange noises and it's shaking!" — Sedine, during a road trip.

"... we stopped rolling. Now we can contemplate the word ... repair ..." — Sam, post-roadside breakdown.

History
Sam & Sedine's primary mode of transportation, their vintage Volkswagen Beetle has been converted to a front-engine vehicle, presumably to increase the amount of horsepower available.

As Sam's mechanical skills appear limited, it remains an open question as to when/how the conversion was undertaken, and who did the actual work.
