Yes it seems to have got very arbitrary over recent years. Fortunately my Plus Four is a 2020, and next time I tax it the surcharge will have expired and it will be far more reasonable - around £200 I think? Likewise the BMW i3 Electric that my wife uses is £200 per year? And my daily - a BMW 740LD is around 200. The final car in the garage is a 2010 Defender 90 2.4tdci Soft top (fortunately converted from a pick up - and classified as a "commercial) which is £350 per year, but would be double that if it were classified as a passenger car.
