One of many glowing reports:
...........The database appears, from some searching on the government site rather than the mash up, and from discussion elsewhere on PH, to be wildly inaccurate. It does appear to include cars subject to a SORN, If it were accurate, it would still be mildly interesting for classics as it would show how many are left now.............
To do this much research via such an unreliable resource into such a mundane model, whilst being this naive, makes you quite entertaining.
Have fun.
