SLK gift

My grandmother decided to leave her car in the garage at the age of 86 and give it to her grandchildren, my sister and me. Now I don’t know if that makes any sense at all. Is it about the SKL first series in disgusting light blue baby color. Apart from the color, I don’t know much about the car at the moment. My grandmother could tell us about the car. The car got a new TÜV badge and didn’t have to go to the workshop due to any defects. I assume, however, that the KM stand should be kept within limits. She bought the car as an annual car about 5 years ago and then drove more and more rarely, due to worse eyes etc. Now I wanted to ask here for tips. How expensive is it? Is it worth it, or do you rather recommend selling the car and then buying yourself a smaller cheaper one? Unfortunately, I have no idea of cars at all and in my circle of friends everyone tells me something different. Let’s see what you can contribute to the decision. Thank you already. Greeting, Max
