What a Piece of Junk!/Playing With

Basic Trope: An apparently-decrepit vehicle turns out to be superior in performance to newer, shinier machines.
 * Straight: Ben's Mini-Mecha is dented and scarred with flaking paint, but its speed and power are visibly better than the other models shown.
 * Exaggerated: Ben's mecha is covered in rust and sloppy jury-rigged repairs, but it can outrun fighter jets while carrying entire freight cars.
 * Downplayed: Ben's mecha is less stylish than the others in the show, but it runs measurably faster.
 * Justified: The company Ben works for is running on a shoestring budget and can't afford nonessential repairs.
 * Inverted: Neb's mecha is a Rice Burner.
 * Subverted: When Ben's mecha breaks down after running circles around his opposition, he switches to a newer model like those he's been fighting ... and is even faster.
 * Double Subverted: ...because his old mecha was actually in dire need of repairs the whole time. When it finally gets fixed and he's back in it, it's even better.
 * Parodied: Deb shoots her mecha full of holes because all the best mechas in her cartoons look beat up.
 * Deconstructed: Ben's mecha is as fast as it is relative to the others because it was built right before new regulations banned the use of its core technology for environmental and safety reasons, and he ends up facing legal charges for continuing to operate it.
 * Reconstructed: Ben's mecha is as fast as it is relative to the others because it was a Super Prototype when it was built -- which explains why the aesthetics ... aren't there.
 * Zig Zagged: Ben's mecha is fast, but unreliable.
 * Averted: None of the mechas are in apparently worse condition than any others.
 * Enforced: Ben is the Cool Old Guy, and therefore must have a cool old mecha.
 * Lampshaded: "Are you sure that'll still run, Ben?"
 * Invoked: Ben prefers his opponents off-guard.
 * Exploited: Barb bets on Ben in a duel, knowing that most of the people gambling will underestimate his odds.
 * Defied: Ben buffs, polishes, and paints his Mini-Mecha religiously.
 * Discussed: "The first lesson you will need to learn is a simple one: underestimate no-one. You see that heap out in the yard there? Ben, show them what it can do."
 * Conversed: "You know, I can't see why the Mooks keep getting fooled by Ben's mecha. Every old model you see is better than the new ones."
