Looking at a Mastiff?
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 Mastiff is off the road? A free SORN check shows whether it is currently SORN, taxed or untaxed.
Is the Mastiff disappearing?
Licensed numbers peaked at 272 in 2023 Q3 and stand at 211 in 2026 Q1, down 22%. That is up 134% in the five years since 2021 Q1. A further 125 are declared SORN — 1 in 3 of the 336 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.
