Is this sentence correct? Than you!

I think I am going to take the sports car to school, If you do, you will be too early.

A couple of points:

1) After the word "school", you need a full stop, not a comma.

2) I'm assuming that 2 different people are saying these sentences. You need to put quotation marks round each sentence.

"I think I'm going to take the sports car to school." "If you do, you'll be too early."
