Purchase advice and 100 questions about the V70 2.5T

Hello, I am looking for a young used station wagon, and I like the Volvo V70 in addition to Mercedes E-Class and Audi A6. Now I have found the following model at mobile.de, for which I certainly have 100 questions …. KLICK What do you think of the price for the V70 in general? OK? Bargains? Normal? On the one hand you are looking for the bargain, of course, on the other hand it is sometimes strange that a car like here is for sale after 14 months and only 14,000km. I am a bit confused by the performance data given in the mobile.de advertisement. There is V70 2.5T and 147 kW / 200 hp. Not only with the car, that is also found with other V70 2.5T. On Volvo.de, however, I find the V70 2.5T only with 170 kW / 231 hp. Just the same CO2 emissions, which are not completely unimportant for the taxes: In the mobile.de listing only about 148 g/km, according to Volvo.de at 2.5T 232 g/km. Are there information about mobile.de or Volvo. Although there was not one wrong?
