S80 T6 Executive 2013

Hello Together At the moment driving a C70 T5 automatic from 2008 with a good 140’000 kilometers and relatively good equipment I discovered a S80 T6 Executive 2013 on the used car market. This one has 127’000 kilometers. What do you think is a change worth it? How rare is the C70 with the T5 engine. How high would the exchange price be? (Switzerland)
