Classic Car Data API

The data nobody else has: labor times, torque specs, and fluid capacities for nearly 15,000 pre-OBD2 vehicles — tri-fives to Fox-bodies.

Commercial data providers start around the early '80s and thin out fast before that — there's no flag-hour revenue in classics, so they never digitized the era. The restoration world runs on out-of-print factory manuals and forum folklore. OLP structured it: 14,000+ vehicles from 1955–1995 with the same API as a 2026 EV.

What you get

  • 14,878 pre-1996 vehicles: 100% with labor times, 96% with torque specs, 100% with fluid specs
  • Era-correct data — points ignition, carburetors, and mechanical fuel pumps where they belong (we purged 600K+ anachronisms)
  • Same endpoints and key as modern vehicles — one integration covers 1955 to today
  • Finished territory: classic specs never change, so coverage only gets more verified over time

Common questions

Seriously, nobody else has this era?

Not as a structured API. Mitchell and ALLDATA exist to bill modern shop hours; their coverage fades before the mid-'80s. Pre-OBD2 data otherwise lives in paper manuals and forums. This is our moat and we maintain it accordingly.

How do you know classic-era data is right?

The same accuracy program as everything else, plus era-applicability sweeps that removed hundreds of thousands of anachronistic rows (no ABS modules on '57 Bel Airs here). Extreme values get owner review; expert verification propagates by engine family.

Do you cover foreign classics?

Yes — the catalog is US-market-centric but includes European and Japanese imports sold here, plus notable gray-market vehicles.
