Buy XC70 used – now or still waiting?

Hello together, after thinking for weeks about which XC70 I should buy needed… D4/D5, four/five cylinders, momentum/summum, … the question came to me today… should I rather strike now, since it is no longer built, or rather wait, because people will buy something new? Although I don’t know what the corresponding successor should be, because the XC90 is a completely different caliber?! I am definitely looking for a newer, max. 30,000km, BJ2013 and younger… Thank you and have a nice Sunday! Oliver
