Fiat Croma 2,4

Hello together, I am new here and in the process of getting me a used Croma 2,4 Multijet Emotion build year 4.2006. Fz. is sold by Fiat dealer. Checkheft maintained, about 50,000 km run still 1 year warranty. Drive e.g. a Bmw E38 which also slowly gets mucken (235000Km). What I have to pay attention if I want to buy the Croma. Read here often intake bridge, gear software and engine control software has been made an update. this workshop was completed???. Otherwise I find it a great car, very comfortable, quiet, fast and good equipment and workmanship at first impression. Maybe there are a few tips from Croma owners who have the Fz. for a long time. Thank you and another nice day Peter from Berlin
