Well, being as you are in the EU, couldn't you go to one of the member states with good incentives like say Germany and save 4k from that, then drive you vechile to your own member state and avail of the single market.
You need to have a registered address or a friend in Germany in order to take advantage of the incentives. The car must be with German plates for the first year, which presents some other problems.
Some German auto dealers are skirting the law by buying EVs, getting the money from the two incentives while keeping the car sitting for some time, then selling it abroad for a bit less than it costs to buy it there.
There are rules against car registration/importing to prevent this. Or else everyone in Western Europe would just buy and register their cars in Latvia/Romania etc.
Just a thought.
