Sell or keep?

Hello together, I have a question about which I just want to get some opinions here. I lack the experience in this regard and I just don’t know what to do at the moment: I am currently driving a Fiat 500, 1.2Pop with 69 hp, built in 2008, 1st hand, 120.000km, TÜV new (until 2015), special equipment: chrome compact, additional chrome-plated exterior mirrors (these are not included in the chrome package), air conditioning, ESP, height-adjustable driver’s seat. Color: red, floor mats (special ready-to-use). ng) + rubber foot mats for the winter The great customer service with timing belt change still needs to be done. 8-fold tires, however, also have to be renewed after this year. The bonnet has some stone strokes without dents, but the varnish has broken off. Therefore looks a bit like a fly mushroom. Apart from that, the car is very well maintained. I now consider whether it is perhaps the right time to buy a new car or not. I have to say that until vo r two years I was a lot driver, meanwhile I drive annually between 12,000 and 15,000 km. What do you think? What do your experiences say: Sell, because there may be even bigger repairs in the near future, or invest again in customer service and possibly paint treatment + new tires and drive the car “to the end”?
