In a sea of flashy rides at the House Of Colors Booth, the 1929 Plymouth Street Rod Diesel stood out like a neon penguin at a tuxedo convention. The color popped like it was auditioning for a superhero movie, but what really grabbed my gears was the engine—a diesel, not the expected HEMI. It’s like discovering your grandma has a secret tattoo. My take on diesel engines? They’re like a good punchline—unexpected, efficient, and they always leave an impression.
