Why isn't this possible for EU residents? Because EU residents are not allowed to drive to car within Andorra or because EU residents are not allowed to drive around with MT plates in the EU?This might not help in your case, but for people residing outside the EU, Andorra has "temporary" MT plates. Andorra has 4.5% VAT, instead of e.g. 19% in Germany etc., so quite a lot of money could be saved. The annual registration renewal can be done remotely with some private service providers.
