looks like they will completely change taxes on autos in 2008.
now the taxes are cheap for Benziner and very expensive for Diesel.
they want to make taxes according to CO2.
that would mean that diesel autos taxes will be a litle cheaper than benzin auto taxes.

That also means that old cheap autos will have expensive taxes.

if anybody knows anything else about these new auto taxes, be free to add it here.
after all it is important to all of us owning auto and especcialy for those buying auto.
it will not be a nice surprice if you are paying 100€ taxes on your auto and next year you have to pay 500€

this is not the new ca tax but only an example now ADAC would do it:

since it looks quite similar to this new law I think I can change the statement above.
meaning benzin car tax will stay cheap and diesel car tax will stay expensive.
