Yes, they are good on gas. They are worth buying. Plus there fast if you want a sporty car!:) if you take good care of them then they will last a longtime!!
If you want to save on gas get a good fuel economy car. If you want a fast car, get a muscle car. You pretty much have to choose one over the other.

Depending on the yr/make/ model of the car you are talking about, it could be... inexpensive good on gas safe fast/fun to drive high payload/towing capacity(pickup, SUV) roomy good off road
it depends what speed is fast and what speed is slow and what car you are talking about.
It all depends on the size of the motor and the amount of cylinders it has.
What causes a car to idle good and run rough when you give it gas?
