Phone got run over by a car, is it worth trying to repair it?

Hi,

my xiaomi got run over by a car. It seems like everything works apart from the display, which is shattered. Touchscreen, back camera, buttons and calls work. I can’t tell for the front camera but i had problems with the camera already before the incident. The frame is broken just a little bit close to one corner. Considering the original price of 150 € it doesnt seem worth paying the 100€ to have the display repaired by a professional. Is it possible that the battery has a damage that is not yet visible? I don’t want it to inflate, explode or burn for example. Also the exchange part alone costs 60 €. I have never done any repairs of this kind by myself and fear to break even more if i lay hands on this phone. Now my question: Is it worth trying to repair it myself or should i rather buy a new phone and spare myself the time and money?

Thank you kindly for your advice!
