So my mom finally bought herself a new car (she's so excited!) and has a van that she won't be using. She said she could give it to me and that would make it my first car. If she doesn't give it to me, she would be selling it to help pay off the new car. The van has a lot of miles on it, isn't so reliable and gets poor gas mileage compared to a small car. Would it be in poor taste to sell it once she gives it to me so I could buy a smaller, more fuel efficient car?
