Aftermarket kit

So, let's say you have a toy car, but you want to make it look different and cooler. Instead of getting a brand new car, you can buy something called an "aftermarket kit."

This kit has special parts that you can add to your toy car, like new wheels or bumpers. It's like getting new clothes for your toy car.

The kit usually doesn't come with instructions, so you might need some help from an adult to put everything together. Once you're done, your toy car will have a whole new look that you made all by yourself!
