$20,000 gift for new car

[schuylkill]

My parents are generously buying me a new car. I commute 160 miles total each day and my 1998 Civic CX currently has 588 K on it and they worry about me in it I guess. Any how they want me to get a new car (not a used car) and
I want to get one that will last and will give me the lowest total ownership cost.
If I were to get a Prius or any car where the total outlay is over $20k I would need to finance since I have minimal savings which I don't want to put into a car. So any advice on how to project total ownership cost over say 10 years?
As for the car to purchase I like hatchbacks but I will keep my cx so I have that. The Prius is interesting but for me expensive. I am happy with my Honda.
I read that the 2012 Civic HF will only be available as a sedan. Any clues about the prices for the 2012 civics? Any suggestions on other cars? Thanks.
