Reliable vehicle for regional transport tasks wanted! Budget 3-4000.-Eur

Dear forum community! I am now looking for an adequate replacement for my S124. The following criteria should apply: 1. Practical – suitable for small transport tasks + AHK. (must not be a transporter – combo is sufficient) 2. Application area mainly short distance small town/country 3. Does not have to be beautiful. (from appearance) 4. Should be cheap up to max. 3-4,000.- Eur and thus hold ~ 3-6 years. (per year ~1000.-) 5. annual km performance ~ 5000km 6. Robust, maintenance-friendly or not Very susceptible (wear parts like brakes, tires,… except – can I do it myself) 7. Spare parts rather cheap – as Japanese/Asian traps mostly out – at least my experience in the past! Now I have already looked a little and considered the following: 1. Fiat Doblo 2. Chevrolet Nubira 3. Nissan Tiida 4. Citroen xsara Picasso Is Astra/Vectra Kombi or Citroen Xsara Picasso what? What recommendation do you have? What is it worth paying attention to? (There are also innerhale) b of a model better and worse engine variants,…) I’m a little helpless – because I don’t really have an overview on the market! (What is problematic or reliable?) Thank you very much for helpful tips!
