Everyone should start out with a car that has no nuts. It's essential to becoming a better driver.
When you start out with very little power, you have to learn to make the most of it! If you have a 300hp car, cornering and braking are not as important as they are in a 150hp car. In fact, launching is not as important in a 300hp car either. In a 150hp car, you have to improve on your skills if you want to go any faster, and I think you gain a deeper sense of car control.
As you add power to the car, the balance of the car changes gradually, and you know exactly when to put that power to use, and still retain the skills you garnered coping with the aenimia of the car's engine.
