For a based guesstimate of the prices in your country, do what @TrevP did (and I copied for The Netherlands). Take the $ and € prices of Model S 75 and S 100D in the US and Germany. Apply those factors to the Model 3 55-SB and 80-LRB. For the German € prices for options, do the same for comparable US options. Of course that is no certainty, but the best guess possible at the moment. For us in The Netherlands it's 40 % more for the car and 6 % more for the options, due to transport costs, import duties and VAT. All factors which Tesla has hardly any grip on. They can only decide that prices are unreasonably high (or low) and will do with less (or more) profit in specific countries, for 3 compared to S, due to marketing reasons.
