930 Turbo Cabriolet & Targa • 1987-1989
These body-style variants offer a separate appraisal tier, appealing to collectors seeking a blend of performance and open-air driving experiences.
Known issues by generation
For the 930 Turbo, understanding common issues is vital for ensuring optimal performance. The 1976-1979 models are known for KKK turbocharger lag, which leads to explosive power delivery, often referred to as the 'widow-maker' characteristic, particularly concerning during lift-off oversteer. Meanwhile, the 1986-1989 variants benefit from an upgraded air-to-air intercooler, but still require vigilant maintenance, including regular KKK turbocharger rebuilds every 80-120k miles and head-stud replacements to prevent failures. Furthermore, the notorious Type-915 gearbox's shift characteristics and synchro wear necessitate periodic rebuilds, particularly for pre-1989 models, while the G50/50 in the last year offers a highly regarded, iron-clad manual transmission option.
Donation value by condition + generation
The collector value of the Porsche 930 Turbo exemplifies the peak of the air-cooled era, with values for 1989 G50/50 models ranging from $150k to $300k, while pre-1989 variants command $80k to $150k depending on condition. Original paint and matching numbers are crucial, as any factory-color change serves as a catastrophic red flag for collectors. The Porsche Certificate of Authenticity (COA) is indispensable for verifying provenance and enhancing value. With qualified appraisals often crossing the $5k threshold and many exceeding $50k, maintaining detailed service records and auction comps from reputable sources like Hagerty and RM Sotheby’s is essential for securing maximum value in the collector market.
