Questions
›What car has a VIN starting with 4S3?
A Subaru built in United States — typically Indiana-built Legacy and Outback. The three characters identify the manufacturer and plant region, not the specific model; characters 4–8 describe the model itself.
›Is 4S3 the same as the country of origin?
The first character alone gives the region — 4 indicates United States. All three together identify the specific manufacturer and division within it.
›Can I tell the model year from 4S3?
No. The WMI says who built the vehicle, not when. Character 10 carries the model year, and character 7 helps resolve which of its two possible years applies.
