Where the Trooper is built

| Assembled in | Share | VIN starts with | Years seen |
|---|---|---|---|
| Japan | JAC, JAA | 1985-2002 |

Trooper generations, and what changed
These boundaries are not copied from a brochure — they fall out of the measurements. Where the Trooper's length or wheelbase jumps between consecutive model years the platform changed: a facelift moves a bumper by centimetres, a new generation moves the whole car — for the Trooper that gives 2 distinct generations below.
| Generation | Length | Wheelbase | Weight | vs previous | Weight change |
|---|---|---|---|---|---|
| 1990-1991 | 447 cm | 265 cm | 1696 kg | - | - |
| 1998-2005 | 459 cm | 276 cm | 1939 kg | +12 cm | +243 kg |
Between 1990 and 2005 the Trooper gained 12 cm in length (+2.7%) and 243 kg in weight (+14.3%). Cars did not so much grow as thicken — crash structures, airbags and equipment weigh more than the metal they replaced, and on the Trooper that is 243 kg against 12 cm. Full dimensions by year →
