Cheap car’s in maintenance! Help:)

Hello dear ones, I hope you can help me, I got the new Mercedes A class last year. Super car, however, the running costs caused me a headache, so that I sold it again and got me a smart year car again. I’m actually totally happy with that now I am pregnant and we are thinking of getting another car. Of course my friend would like to drive Audi or BMW, because I pay the car and it will run on my name I want to I would like to ask you what you could recommend to me, in maintenance/consumption, cheap cars? Would you like to drive a 1-3 year old car again and it doesn’t necessarily have to be a big car, small cars with more than 2 seats would be great)) Hope you can help me find something suitable, with which man and woman would be satisfied! Thank you! Mily
