Can you help me find the model year and maybe give me a price for this Cube bike?

10 speed Ultegra makes it 2010ish. By 2013 Ultegra was 11 speed and before 2008 the shifting cables exited the shifters at the top. If you want an exact year step through the years in a Google image search. Probably 500-600 euro but regions can have different prices.
