I take the point that it's not just 4x4s affected - that is why I said in my opening paragraph "4x4s and other large cars".
HOWEVER, in caravanning terms, many of us who tow biggish caravans are buying 4x4s because they are more capable in terms of lugging and higher noseweight.
So on this Forum, I am talking in terms of that fraternity and for them it is bound to make them think whether they can justify buying another 4x4 at their next trade in.
Since other 4x4 drivers, who don't need them, will be offloading them in droves then the bottom will surely fall out of the market.
That's bad news for those who have bought a 4x4 since March 2006 and bad news for car manufacturers trying to sell them new. But it's good news for those of us who bought before March 2006 and good news for anyone who wants to pick up a second-hand one cheap (providing they're prepared to pay the higher taxes and ancilliary penalties).
Me, I can't complain. My 3 litre diesel 4x4 auto will be taxed at only marginally more than my Corsa 1.4 petrol auto...! If Gordy was out to bash big car owners, he's failed miserably...
