The 1978-1981 BMW 323i Baur Convertible (E21 TC-1) is a rare, Baur-prepared version of the E21 3-Series, often referred to as a "targa" or "top cabriolet." It features the desirable 2.3-liter M20 straight-six engine, producing around 150PS. Enthusiasts prize this car as a sought-after modern classic for its rarity (only 1,543 323i Baur units were made), unique design, and sporty handling that set the stage for future BMW generations. It is famous for being BMW’s factory-approved open-top E21. Today, it is best suited as a collector's item or a classic weekend cruiser.
BMW 323i annual maintenance averages $487–$717. Reliability concerns include the cooling system, various gaskets (valve cover, oil filter housing), and electrical issues. Be prepared for preventative maintenance on aging rubber components.
