Search vehicle for 60tkm per year / 3,5T€

Hello I need a “new” vehicle again. Since you drive at least 60tkm a year (80% AB) a diesel will charge for me. Only the question is much better? I have 3.500 euro as a budget and what he should have is cruise control and an AHK would not be bad (could I also retrofit myself) Since it is not much money the selection remains frighteningly low. Especially since I hope that the car should last for at least 2-3 years. As a preselection I have found the following models: Citroen C5 110HDI Bj2005 155t km Alfa 159 1.9 JTD Bj 2004 180tkm Mazda 6 2.0 CD Bj 2003 150tkm VW Passat 1.9 TDI Bj 2001 180tkm Mercedes C200 Bj2000 190tkm These are now only so rough the average price what you find, of course, some offers (private / dealer) & equipment variants vary. Euro3/4 What would interest me now is your experiences about the engines. I don’t want to ask the same question now at every manufacturer forum. That’s why I try here in general. i with the rust death or similar die I think rather less. When I look in the net I find that all manufacturers have the 360tkm and more. Only unfortunately there is rarely there what had to be invested so far. I know the FAST every engine can create 600tkm, but does this bring me if I had to change turbo x times, if necessary the pistons renew careers honen, ZMS renew etc.?! So which diesel from the years 2000 to 2006 really durable and for 3.5T with a coach? I hope you can get a little light into the dark
