Toyota Rav4 2.2 diesel 150ps bj. 2012 Purchase advice

Hello together, I intend to buy a Toyota Rav4 bj. 2012-2013. It should definitely become a diesel with four-wheel drive. Now my questions to the community: How good is the 2.2L 150ps diesel engine? Does it count as reliable? How often do you have to change the longlife oil? What does it consume on average?(7-8 liter?) What about the transmission? Manulles or rather automatic? What intervals are there when changing the transmission oil? I intend to change the car over 200tkm to drive, is the automatic transmission the right one? Thank you already before Greeting Konstantin
