964 Valuation Calculator
The same calculator as the homepage, with the working shown. It values a car from verified sales of the same model, body, and transmission in the same mileage band — nothing else.
What is this 964 worth?
Every car is valued from sales of the same model, body, and transmission. Nothing is averaged across the range.
Pick the car, enter the mileage, and run it. If the band doesn't have enough verified sales yet, the calculator says so instead of guessing.
How the number is built
Sales from 2019 on, with documented mileage, sit in bands: under 15,000 miles, 15–30k, 30–50k, 50–75k, and 75k+. Cars with substantive modifications are left out of the bands; cosmetic changes (a head unit, wheels, clear markers) are not.
Three or more sales in a band produce a median. One or two sales show their actual hammer prices instead, labelled as observed prices. No sales, even after widening once to the same model and body across transmissions, and the calculator says there isn't enough data. It never fills a gap with a guess.
The suggested private-sale ask is the adjusted median plus about $3,500. Auction hammers run below asking prices, so the ask starts higher than the number the band produced.
Adjustments
Documented items that should move a price — engine reseal / top-end documented, flywheel replaced, distributor vent kit fitted, sport seats — are listed on the form. Each one launches unmeasured: until the 964 dataset itself produces a defensible number, the calculator names the item and applies nothing. Made-up percentages would be worse than none.
