SL 55 AMG import from USA ???

Hello, would like to buy a Mercedes SL 55 AMG from my uncle soon. The car would cost me about 25000 €. Now is my question: What costs would be added to the purchase price and are there any tricks on how to avoid these costs or save yourself ??? Have heard that there are taxes and VAT or similar. If someone can help me further, I would be very grateful. Thank you Sakis
