My car model is Hyundai Avante. Its color is white and it is an ordinary family car.
When my son was born, we bought this new car, which is safer and cozier. So it’s as old as my son/ the two are same aged.

Doesn't the two are same aged. sound awkward, which is comparing a person and a thing?

Say:

The two are the same age.

When my son was born, we bought this car new. It's as old as my son. The two are the same age.

I would say:

I own a Hyundai Avante. It's white and is an ordinary family car.

I would say:

I own a Hyundai Avante. It's white and is an ordinary family car.

What is the difference between the two? Does one mean "bought something anew", while 2 doesn't makes sense as it's not a new any more as of now?

1.When my son was born, we bought this car new
2.When my son was born, we bought this new car

They are my own making.

So why would you purposely write something that you think doesn't make sense?

I don't purposely write wrong, I only make mistakes.

No. You said that you wrote the second sentence yourself. You also said you think it doesn't make sense. That means that you purposely wrote something that doesn't make sense.

It was because I didn't know any other way except this.
