I wouldn't get too hung up on the German pricing. That €37k price is for DSG, manual will be cheaper. £33k is the same price as the outgoing 7.5 GTi Performance with DSG.
From another perspective, the 1.5 eTSi in R Line spec is €33,230 in Germany, or when converted into the Queens pounds = £29,749. UK list price is actually only £28,705, roughly £1k less than the German price converted into sterling.
