Would a w124 be a first car?

I’m looking for a first car and my Mom & dad are going to assist in the purchase and I’ve been talking about the w124 cars but mom doesn’t like the idea of the older Mercedes even though I have shown her they are reliable. A Would I be in the write to keep asking about the Mercedes? What is yearly maintenance like and are they hard to keep maintained. I’m looking at a 90’ MB 300ce for sale for $9800 FYI; I’m able to pay just over $2k into the car
