VAT is an issue; so is the exchange rate. I was active-duty US military in Germany, and frequently used VAT forms to eliminate the tax, which was around 15 - 19%, depending on which country in which I shopped (Germany at the time was 17%; Luxembourg was the bargain at 15%). When the Euro was introduced, VAT was standardized and remained at something like 17% throughout mainland Europe. The exchange rate went from about $1 = E1.20 to about $1 = E0.80 (the dollar got weaker), but I don't know where either stand today. I left Europe for the final time in 2012, but I was able to purchase several BMW items far cheaper than I would have in the US. Quick example is the convertible windscreen that fits behind the front seats. I paid about $165 for mine, new.
You would have to know the current relative strength of the Euro (I'll look it up later), and I suspect the current European VAT is charged regardless of destination. But I do think you can find items cheaper there--as long as you know the item's Stateside price, you can compare.
