30k budget for 25-30tkm long distance with low value loss sought

Hello together, many infos are already in the title. I am looking for a vehicle that meets the following criteria: – purchase cost max. 30 TEUR – annual KM-performance 25-30,000 km – primary long distance on highway – as low as possible value loss (I hate to burn money) – “reasonable” maintenance costs. Car should be less than 300 EUR per month incl. all costs. – Space offer: ride mostly alone, but am 1,93m grpß The car may be used, but should then be over So far in the race are: – Golf GTD – BMW 118d, 120d, 318d, 320d – Audi A3 TdI – Nissan quashkai Diesel (I like SUVs) So far it seems most useful to me to buy a 2 year old car with a mileage of up to 30 tkm. Reasons: – the first big loss in value is gone – cars with warranty still available – when selling after approx. 2.5-3 years the car then (ideally) has run still under 100tkm, can be better sold again if necessary. tips? 😉 Thank you very much in advance!
