Just a quick note on converting Euro prices in to GBP - the Euro is really strong against the pound at the moment, so you'll get what seem like rather high prices if you just do a straight conversion.
I haven't looked in to it myself, but I'm guessing if you convert the prices of cars currently available in Germany and the UK (say a 2.0 TDI 3dr Sport etc) you'd find the prices don't match based on today's exchange rate (if you convert from Euros to Pounds you should find that the actually UK retail price is less than that calculated price).
So don't get too panicky about the S3 costing 33k rather than 31k etc, at least not until the prices are released in the UK.
Also worth bearing in mind that they don't have to sell them for the same price e.g. If a manufacturer decides a market can/can't swallow a certain price point, they will tweak the price for that market.
