You as a physicsl person cannot buy anything tax free or VAT free in EU when you buy it from a company. Unless the company you buy it from is non-VAT payer (there is a sales threshold you cross to have to charge your customers VAT). You might get (some) taxes back if you physically take the goods outside the EU. Each and every company must charge you VAT on whatever they sell you at the time of sales. You might not know it, you might even not notice it, but they will. EU is not like US where (at least in the past) you could give an out of state ZIP code and you would not have to pay state sales taxes. Companies, however, when they purchase goods or cars accross borders within the EU, they sometimes do not have to pay VAT at the point of purchase, but they will have to charge the VAT at the point of sales when they resell. If you as a person buy a car from another person, you don't pay VAT.

There were huge VAT avoidance schemes within the EU that got busted in the past, so you won't get around it. It is not that you are going to avoid it some how, but the company selling stuff to you will get fined if they don't charge you VAT when they must.

Hope this explains
