Cheap car for work journey and WE commuting

Hello, I’m looking for a car for 80KM (both ways) working day and WE commuting trips of about 330KM. Most likely I won’t drive the paths every day and every WE, but surely a few (rather a few) short trips and a few longer vacation trips will come along. Think about the 25T KM overall. Of this is the bear share (about 80-90% AB). Rest stop city and country road. Budget is about 6K. I would like to have warranty from the dealer, since a diesel after all apparently low consumption costs are the top priority. I don’t care about brand and class. Tempomat would be nice, but no need. Likewise, the automatic circuit (thinking is not advisable with Prio consumption and the budget?) climate should be in the budget. A semi-comfortable driver’s seat (back gentle) would still be important to me. The rest is really not important. So again summarized: – KM approx. 25T/year – brand, class no matter – 90% AB/10% LS, city – low maintenance costs (insurance, tax, fuel) – Optional cruise control – Midway comfortable driver seat (backside gentle) at 1.90m size – PS is not so important and depends on the size. Have no problem with weaker engines, if the consumption is thus very cheap – Green badge – warranty So, I think that all information should be. Already many thanks in advance and nice greetings edit: e.g. the hereOpel Astra 1,3 CDTI
