No, probably. It depends on the price of the materials you use. It's a value added tax. It taxes the value that you created.
Lets say you buy €5000 worth of steel and then make it into a car that you sell for €10,000. With a 20% VAT rate the government gets €2000 and you get €8000.
However, that steel you bought also included 20% VAT in its price (€1000). You get this money back from the government. The steel actually cost €4000 for you.
In total your profit would be €4000. Effectively, the 20% VAT applies to the €5000 of value that you created.

If you built that Ford Fiesta outside of the EU then the "value add" is the entire price of the vehicle. But you don't have to pay VAT for the raw materials you buy, so theoretically it should end up being the same amount of profit.
