Any idea what it is that makes them not fit?

Emissions and crashtest. It's OK to import an old car, eg. the E-type, because it has allready been registreted in Denmark, when it was first launched. But when you take a car that hasn't allready been registreted it has to live up to the current spec.

It is. Finland (another absurdly-high-car-tax country) has already started adjusting the tax down in anticipation of harmonization. And the technical exemptions are temporary too. Brussels is definitely driving for pan-european rules.

Oh yes, trust me - i'm following the discussion in Denmark very close on this matter. Allready now there is a tiny loophole. If you've lived in another EU country, you are now allowed to take your belongings with you import and tax free if you paid tax and what not in the country you came from. You only have to live out of Denmark for six month for this to apply. Ofcource, that didn't come by it self, there had to be a trial against the Danish state in the EU for this to happen. But we're getting there in small steps. There is only one thing you can be certain on, the at all time sitting goverment will have to find other ways to collect taxes, so it's not gonna be cheaper to be Danish.
