These stats have come from an extract of DVLA data up to September 2005, a few months before the last UK A2 was registered.
They have been produced in response to various queries over the years on the A2OC.
The data is not 100% accurate! In particular colours and engine capacities has some strange values.
Note: 66 vehicles excluded as the engine capacity data was invalid
Note: there was a major error in the extract data. It appears that all the metropolitan districts data was classed as "not known". These areas are coloured green (no data) on the map.
