An email that I received two weeks ago outlining some of the proposed changes and a link to a survey included an annual milage reduction to 10000 per year and 28p per mile over, 4 replacement tyres instead of the present 8 per lease and a reduction in named drivers for insurance purposes also no European breakdown cover.
I can see uplift in sales of Ling Long or Nankang tyres on the horizon, especially as some cars eat tyres more tha others.
Likewise, if what you say turns out to be true, it will be worth cross referencing private lease deals with the scheme especially if you have a credit rating.
