I Need A Car

Hello there! I'm 17 and I need a new car. I currently have a 2000 Honda Civic EX and I have loved working on it! However, it's time for me to move on. I need a car that I can find for around 7k. It can't be a jeep, truck, or sports car (duh) because my insurance would go up. I'd like for it to not be impossible to work on, as I love doing work on cars. If anyone has a good idea, please let me know! I don't want it to be fast, just quick, the only speed I really go for is stop light racing, and that's rare. I'd like good gas mileage, it doesn't have to be great, maybe around 20mpg. Thank y'all!
