Looking at a FAT Sabbath?

Population figures cannot tell you whether one particular car is taxed, MOT-valid or safe to buy.

Check its registration free for the official tax, MOT and mileage record. If the car is still worth pursuing, the optional £9.99 full history check adds outstanding-finance, stolen and insurance write-off checks.

Wondering whether one particular FAT Sabbath is off the road? A free SORN check shows whether it is currently SORN, taxed or untaxed.

Is the FAT Sabbath disappearing?

Licensed numbers peaked at 507 in 2023 Q2 and stand at 352 in 2026 Q1, down 31%. That is up 51% in the five years since 2021 Q1. A further 290 are declared SORN — 1 in 2 of the 642 still on the DVLA record is off the road, laid up, part-restored or waiting to be sold.

A falling population is worth knowing before you buy: it usually means fewer donor cars, fewer specialists and slower parts supply, and it is why a good example of a scarce model can hold its price while a neglected one is hard to sell at any price.
