Citroen C3 – good and cheap?

Hello you, I need your help with buying used cars. In advance: I can drive a car, but technically I am a zero. I have no idea what I have to pay attention to with the carts, apart from mileage and co. Since I have quit my service car, I would like to buy a cheap used car in the future. Priced up to 5000 euros. Have two offers here now and would like to hear your opinion: Citroen C3 Exklusive EZ 2003 ca 87000 km 1.4l, 54kW /73PS 1st hand, checkbook maintained, electric window lifter, cruise control, air conditioning, seat heating, NSW, etc. Price from the dealer 4.400 Euro + 1 year warranty Is this even serious? Seems to me “too” cheap. Did I want to look at the car at the end of the week – is there “Citroen-specific” what to consider? Alternative to this would be a Corsa C for 4950 Euro – about the same KM stand, a bit leaner in the equipment, but also stackbook maintained with all inspections etc. .. would be directly around the I would need a reliable car, where I have as little trouble as possible. I would also be willing to take the Corsa for more money with less equipment if you think that the Citroen is too maintenance-intensive or similar.. I have left out automatic car in my search so far – I would like to spare myself a defect in the automatic.. But how about the Citroen – can one strike without hesitation?
