<human>: Can you give me a shortened version of the text?

Well not knew and still looking but story is I'm a car guy/nut. I've owned 4 crappy cars over the year of having a license. I paid for my 3 cars, a 97 Infiniti, 96 Taurus, and a 97 Volvo. Well my current car, the Volvo is on it's last legs. When I confronted my parents about this they felt bad that I helped out so much for the family they want to get me a newish car. Something like 2009+. They want me to just pay the monthly payments and insurance. I pay for my own insurance every month so it won't be much of a hassle. But there's a part of me that will feel bad if I get a newer car. Even though I told my dad about this and he said "it will be yours but also the whole family", I still feel bad. 

I really don't understand how helping out my own family when we live under the same roof makes me deserve a nicer car than what I currently have owned lol.
<bot>: Parents want to buy me a new car because I always help the family. I feel bad. What should I do?
