S60 R Price question

Hello, my current S60 2.4 has accompanied me very reliably the last 1.5 years and 30tkm and I am basically very satisfied with it, but what bothers me a little bit (in addition to the dreary color combination) is the nevertheless a little weak engine. Not that one would be undermotorized with the 170hp, but sometimes a little more bangs would not be wrong already. I would have bought a 2.5T already at that time, but unfortunately at the time no specimen was available, which my specifications on Pr Now I came across a R more or less out of boredom while browsing, and I found that this is a rather nice little wackling, which is technically nevertheless quite different from the normal S60. The specimen, which I am looking at, is 6 years old (but Facelift), has run almost 70tkm and has a neat equipment (Navi, natural leather) and is supposed to cost almost 21t€. That seems to me a little expensive in view of the age, alldi ngs are too few copies on the market to really make a comparison, also Dat and Co. often provide only insufficient clues (I came with the standard rating to about 13500€, which seems to me in return much too low). A 2008 T5 with about 50tkm would have e.g. for about 18t€. What price do you think is appropriate? Greetings, thunderbolt
