AMERICAN GRAFFITI 1964-1/2 FORD MUSTANG CONVERTIBLE BLACK 1:18 SCALE. Mine is hardtop. Note: The instruction says not to translate product names, titles, brand names, model numbers, or other proper nouns — keep them exactly as written. We must translate the description, but keep proper nouns intact. The given text includes the title "AMERICAN GRAFFITI 1964-1/2 FORD MUSTANG CONVERTIBLE BLACK 1:18 SCALE. Mine is hardtop." We should translate the rest: "Mine is hardtop." Keep proper noun sentence intact. So translation would be: "AMERICAN GRAFFITI 1964-1/2 FORD MUSTANG CONVERTIBLE BLACK 1:18 SCALE. Mój egzemplarz ma hardtop." In Polish "hardtop" is maybe "hardtop" or "z twardą dachówką"? Better to keep term if it's model term; but it's English. The instruction: do not translate product names, titles, brand names, model numbers, or other proper nouns — keep exactly as written. "Mine is hardtop." It's not a proper noun; but "hardtop" is a term—should we translate "Mine is hardtop" to Polish "Mój egzemplarz ma hardtop." That's translating the phrase, fine. So final: first line unchanged, second line translated. Also preserve line breaks. So: AMERICAN GRAFFITI 1964-1/2 FORD MUSTANG CONVERTIBLE BLACK 1:18 SCALE. Mój egzemplarz ma hardtop. But original had period after SCALE. Then space. It's single line then "Mine is hardtop." We'll produce: AMERICAN GRAFFITI 1964-1/2 FORD MUSTANG CONVERTIBLE BLACK 1:18 SCALE. Mój egzemplarz ma hardtop. All in one line or two? The original had a space then "Mine is hardtop." It's same line? It appears as one line: "AMERICAN GRAFFITI 1964-1/2 FORD MUSTANG CONVERTIBLE BLACK 1:18 SCALE. Mine is hardtop." We'll keep as one line but with translated second sentence separated by space. Let's output: AMERICAN GRAFFITI 1964-1/2 FORD MUSTANG CONVERTIBLE BLACK 1:18 SCALE. Mój egzemplarz ma hardtop.
