Borgward Isabella classic cars for sale

History of the Borgward Isabella

The Borgward Isabella represented the post-war resurgence of the Bremen-based Borgward company. Initially introduced as the Hansa 1500, the model adopted the Isabella name in a story now woven into German car folklore: its eventual name was first used as a prototype label rather than brand intent. From its market launch in 1954, the Isabella quickly established itself through its modern appearance, technological layout, and broad appeal. The Isabella’s success was immediate—over 11,000 cars produced in the first year alone—and its reputation was further cemented by the variety of body styles released, from limousines to cabriolets and estate versions. The Isabella’s run concluded in 1962 following the bankruptcy of Borgward, with over 200,000 examples having left the Bremen works.

Model History and Series Development

The Isabella’s history began as an evolution of the Hansa 1500, inheriting and improving upon its forerunner’s features. Early production carried both names, but by 1957, Isabella had become the standard. The lineup would expand rapidly: 1957 saw the launch of a more streamlined 2+2 coupé, considered by enthusiasts as the highlight among Borgward’s creations. Other significant versions included the Cabriolet by Deutsch of Cologne, the estate (Kombi), and the Combi model, which was mostly produced for exports, especially to the US. There was no direct successor; the Isabella’s legacy stands alone as Borgward’s swan song in mid-size saloon production.

Highlights and Unique Features

Borgward’s Isabella featured a self-supporting monocoque body, an uncommon approach at the time, praised for its contribution to interior space and stability. Hallmarks included an effective hydraulic clutch, standard four-speed column shift, and a stylish chrome trim enhancing a curvaceous silhouette. Comfort was elevated with two-tone seats—often leather with contrast stitching—and an Art Déco dashboard complete with ribbon speedometer and gold-tinged controls. Accessories such as a factory sunroof, whitewall tyres, radio (sometimes now upgraded to modern specs), and optional fog lamps were available. The Isabella was not just advanced mechanically, but became a style leader, bridging practical function and 1950s-1960s automotive design flair.

Technical Data

Special Editions and Collectible Models

The most celebrated Isabella is the 1957 Coupé, acclaimed for its harmonious design and regarded by many as the most visually appealing Borgward. Cabriolets by Deutsch are especially rare—owing to complex monocoque modifications—and fetch particular attention from collectors. The estate version, Kombi, and export-only pickup models stand out both technically and in terms of market rarity. Models equipped with a factory steel sunroof or rare accessories command further interest in enthusiast circles.

Weak Spots and Common Issues

Potential buyers should pay particular attention to the condition of the monocoque structure, as rust can affect critical areas, especially in unrestored cars. Convertible and coupé versions, due to their unique structural adaptations, may require inspection for body integrity and proper repair work. Spare parts availability remains generally positive, thanks to a devoted enthusiast network, although finding period-correct trim elements and original accessories can be challenging for perfectionists. As with most classics, mechanical components benefit from regular use and attentive upkeep—original documentation, such as factory maintenance manuals, is a plus.

Engine and Performance, Transmission and Handling

The Isabella is distinctive for its solid, confident road handling and responsive steering, aided by a well-engineered independent suspension. The hydraulic clutch and synchronised four-speed transmission support flexible driving in city and country settings. The TS specification with 75 PS allows for lively performance within its era, and well-kept examples impress with their braking performance, balanced ride, and agility for long, brisk drives. Noteworthy variants include the Isabella TS (offering robust performance), the elegant coupé, and rare convertibles—all with technical features outlined above. Each variant maintains the strong mechanical foundation and comfortable driving experience that define the series.

Interior, Comfort, Exterior and Design

Isabella interiors mirror the optimism of its era: two-tone colour schemes, saddle-shade or dyed leather upholstery—often quilted or with contrasting stitching—offer both period flair and comfort. The dash, with its ribbon speedometer, chromed switches, and gold highlights, is a particular talking point for enthusiasts. Outside, the Isabella’s profile is defined by its flowing roofline and harmonious rear design, especially in the coupé. Two-tone paint and chrome trim underline the model’s contemporary tastes. Optional extras such as steel sliding roofs (particularly for the coupé), whitewall tyres, auxiliary lights, and period-correct radios (sometimes now modernised with MP3 inputs) create further individualisation, reflecting the diverse customers the Isabella attracted.

Other Notable Features

Frequently, vehicles have been retrofitted with period safety features such as rear seatbelts and aftermarket side mirrors. Many listings show evidence of careful restoration, with original documentation, workshop manuals, and preservation of classic details such as the unique Art Déco dashboard and bespoke trim inserts.

Summary

With over 200,000 built, the Borgward Isabella is not only a pivotal chapter in German automotive history, but also a distinctive highlight for collectors seeking a blend of advanced design and cultural resonance of the 1950s and 60s. Saloon, coupé, or cabriolet—the Isabella’s unique engineering, comfort, and iconic styling continue to attract enthusiasts, ensuring its legacy remains strong in today's classic car market.
