Purchase intention XC70III D5 – some questions

Servus together! I don’t have one yet, Volvo, but I want one! 😉 I hope that I can still bother you with my questions here! I have looked into the XC70, which I just like. Test drive has already been completed, so now the family is convinced (OHL, two boys and soon a dog). And already we come to the first question: I am a D5 with GT, but the with 175(?) PS. the “big” D5 was not available for a test drive at two dealers – also in no other car. So I would be interested, whether here in forum someone drives this car with the 205 hp D5. Driving impressions (compared to the other D5?), consumption, GT or switch, etc. Secondly, the Gt was very hectic to me. Minimal desired accelerations were only given to me once with a switching time. Since the thing should be learningable – remains that way? or will it be better at 1500rpm in the city, he should not be able to turn on my mind?
