How much the average value has moved over the last 365 days.
Where the 2-year trend points a year from today. Arrow indicates the last 90-day change.
Listings since the start of 2024, plotted as a percent of MSRP with buyer’s fee. Average values are calculated at the end of their respective 2-year trendline, shown as points every 3 months on the dotted black line. Pacing indicates change over the last 90 days relative to the most current trendline. Peaking is defined as an appreciating slope pacing down, and flattening is defined as a depreciating slope pacing up. Triangles represent reserves not met, which are factored into the values.
Listings from the last two years, plotted as a percent of MSRP with buyer’s fee, with a single exponential trendline. Low miles and high miles defined as the 10th and 90th percentiles, respectively. Triangles represent reserves not met, which are factored into the values.

Flat Six Figures started while I was in the market for my first GT4. What began as a simple spreadsheet — tracking values, figuring out what to pay, when to buy, and generally justifying the “guy math” behind buying a Porsche — quickly became something much bigger.
I kept adding more data, charts, and analysis, then expanded into 911 variants. Before long, the project had outgrown its shared spreadsheet entirely. So I taught myself how to build a website with AI and automated as much of the process as possible.
There’s still plenty of daily, hands-on data entry behind the scenes, so I genuinely appreciate any support. If this helped you in any way and you wanna say thanks — buy me a coffee!
