The Puma bit would explain it Doug - EU regs require new vehicles ( post 2006 ?) to have forward facing seats. The Tithonus vehicles are retreads of the older defenders, so can be upgraded but still retain bench seats, the Wolf fleet pre-dates the Regs an'all.
We have two newish "white Fleet" Puma 110 SW, the fold up rear seats are pretty useless and take up most of the load-space. Daft to think that a vehicle that used to have up to 12 ( uncomfortable...) seats is now down to 7.
