Not really: they have been broadly flat. As of Nov 2, 2026, adjusted for trim and model year, Porsche 356 prices over the last 12 months were broadly flat (-3% a year) (123 online-auction sales); over the last 3 months the mix-adjusted median moved +12% against the 3 months before (within normal sample noise), with the raw median at $117,500 against $100,500, and our market signal reads Hold (no clear move).
Within the 356, rising fastest is the Porsche 356B (+22%/yr); easing most is the Porsche 356C (-30%/yr).
Quarter by quarter (online auctions): the median was $117,500 in Q3 2026 (40 sales), against $121,500 in Q2 2026 (38 sales), a -3% change. Quarterly medians move with the mix of cars sold, which is why the headline answer uses the mix-adjusted figures.

Monthly medians and the 3-month windows
Which 356 cars are rising?
| Page | 12-month trend | Sales (12 mo) | Signal |

| Porsche 356C | -30%/yr | 30 | No signal |
The same mix-adjusted 12-month trend as above, computed separately for each sub-generation or trim with enough dated sales. Smaller samples swing more.
How we measure the trend
The 12-month trend is a robust (Theil-Sen) slope of sold prices after removing each sale's trim and model-year effect, so a run of pricier cars does not look like a rising market. The 3-month change compares the mix-adjusted median of the last 3 months with the 3 months before, and the Buy / Hold / Sell signal needs at least 15 sales in each window and a move of 8% or more. These are the same numbers as the market signal on the Porsche 356 page. It describes recent auction results; it is not a forecast or financial advice. Methodology.
