MonzaHaus Index · v1
Fifty years of forced induction. Median sale prices for the Porsche 911 Turbo across seven generations — from the 930 widow-maker to the 992 Turbo S — in a single cross-generational curve.
The MonzaHaus Porsche Turbo Index tracks median hammer prices of Porsche 911 Turbo and Turbo S sales across all seven generations: 930 (1975–1989), 964 Turbo (1991–1994), 993 Turbo / Turbo S (1995–1998), 996 Turbo / Turbo S (2000–2005), 997 Turbo / Turbo S (2007–2012), 991 Turbo / Turbo S (2014–2019), and 992 Turbo / Turbo S (2020–present).
GT2 and GT3 variants are excluded from this index and tracked separately in the forthcoming MonzaHaus GT Index — their racing pedigree and pricing dynamics differ enough to warrant their own series.
Why a cross-generation index: the 911 Turbo is the only Porsche model line continuously produced for 50 years. Cross-generational comparison reveals which eras are over- or undervalued relative to their peers — essential context for both first-time buyers and experienced collectors sizing a position.
