Additional there is no NOVA tax to be paid for ev's, as it is for ICE cars (based on CO2 emissions and can be up to ~36% = 30% + 20% vat).
The benefit of € 5.000,- (2k & 3k) is correct, but you have to own the car for 4 years otherwise you may have to give back some of this money.
Another benefit here in Austria is that there is no additional insurance tax on the liable insurance, making it cheaper as for ICE cars.
Regarding costs, the price in Austria already reduced by this 5k is higher than in some other countries on the continent. But it's hard to compare as most countries do have some kind of subsidies or just other tax regulations, like no vat for ev for example.
BTW: Austria had in 2023 the 2. highest inflation rate within the EU, which makes comparing prices not easier)
I got my xpower about one week before you, but I never read or heard about getting a charging card from MG with 2k euros of credit. Not on the MG Austria homepage nor from the dealer and there was none in my mail until today.
I only know german MG customers got such a charging card of an energy supplier with 3k (?) credit last year.
How did you manage to get this card?
