Find cheap diesel

Moin dear motor talk community, after my old car has given up my mind, I am now looking for a new one. Since I am traveling about 20000 to 25000 km a year (8000 km of highway, the rest of the highway, I am also not the type that drives permanently 130, and fills about 2000 km of city) it should be a diesel from year 2000 which should not cost more than 3000 Euro. Whether now 2 or 5 doors is really not important to me, climate would be good. If possible so around 150tkm and fresh TÜV. AB S etc are of course natural. I have already looked around a bit and picked out the following models, mainly from the VW group, i.e.: Seat Ibiza, Leon, Skoda Fabia, VW Polo, Golf I know that the tdi’s are good but most always want a lot of money for it. cheaper while probably astra, corsa or clio but I don’t know what it looks like with the durability. the sdi’s are m.e. with the few torque a little weak. Opel and so on? You might think of something more useful.
