make enum Only this manufacturer — models are guaranteed to be real models of that make. Omit for a mix.
Coherent fake vehicles: real models per make, era-correct years, standards-valid VINs (ISO 3779 check digit) — filter by make, body type, fuel and year.

} Generates vehicles that hold up to scrutiny instead of random word soup:
make=toyota record is always a Corolla, RAV4, Hilux… never a made-up name or another brand's model. Model pools also carry the body type, plausible fuel options and an approximate first model year, so a Tesla Model 3 never appears as a 1995 car and tesla is always electric (asking for make=tesla&fuel=petrol is an honest 400).year, and the make's real WMI prefix (Tesla VINs start with 5YJ, Volkswagen with WVW).licensePlate is a deliberately generic ABC-123 fantasy format (no real country's scheme), and minYear/maxYear genuinely bound every generated year.Impossible filter combinations (a Toyota estate, a Tesla older than 2008) return a clear 400 naming the conflict — never a silently wrong record.
Structurally yes — 17 characters with a correct check digit, so VIN validators accept them. They don't correspond to real vehicles.
make, type, fuel and minYear/maxYear all genuinely filter — build an all-electric 2020+ fleet in one call.
Yes — models are drawn per make, so you'll never see a Toyota Mustang. Dealer-demo data stays believable.
Fake e-commerce products with category-themed names, prices in real currencies (whole yen for JPY), valid EAN-13 barcodes, SKUs, ratings and image URLs.
Fake account transactions with realistic merchants, weighted statuses and currency-correct amounts — filter by type, status, amount range and date window.
Fake companies with locale-aware names, industry-flavored catchphrases, founding years, log-distributed headcounts and safe example.com websites and emails.
