Moin together, I would like to say in advance that I am not very experienced about cars. I bought a Seat Mii (built in 2014) 1.0 gasoline, 60hp, with 56 thousand KM for 6000 Euro. Now a relative does not want his Citroen C4 (2014) 2.0 diesel with 115hp and 190 thousand KM and offers me to give it to me. I now consider whether I should take the C4 and sell my Seat Mii, optimistically, for 5000 Euro. Although the C4 has v A diesel, which consumes less than 5L, will probably make long distances more pleasant and you only have to roll all 1000KM to the gas station. Of course, the risk is that the engine will give up, that wear will be felt elsewhere or that I will have to spend the money won by the Seat Mii for repair costs in order to drive a Citroen afterwards. What would you advise me to do? Are there any alternative suggestions? Thank you in advance for your answers!
