How to say "convertible" in Japanese

Choosing the right word

可変かへんCommon
na-adjective, no-adjectiveCovers the abstract sense of something changeable, adjustable, or convertible between states, such as variable settings or configurations. For a convertible car this is not the usual word; think 'variable' rather than 'cabriolet'.
オープンカーCommon
nounThis is the word for a convertible car — an automobile with a retractable or open top, also called a cabriolet or soft-top. Use it whenever 'convertible' refers to the vehicle.
私の新あたらしいアルファ・ロメオのオープンカーは明あかるい赤色あかいろだ。↗
My new Alfa Romeo convertible is light red.

Use 「オープンカー」 for a convertible car; 可変 covers the general sense of changeable or adjustable, and is not how you refer to a top-down automobile.
