Alot of good opinions in here but to echo what alot of others have said...if it's paid for and you enjoy it, keep it.
You definitely need to find some balance of kid time and cobra time. Believe me you have more time now than you'll have when they get bigger and start sports. I have 3 kids 12, 10 and 6. We are constantly running around between wrestling, basketball, dance, gymnastics, swimming and baseball. My wife and I NEED the car as a mental escape from the rat race of life.
