「タッタッタ」って車に乗ってみたいな。

This な, what is it? It can't be the colloquial version of ような I guess. So I think it is みたい plus な. But in this case, I don't know what it shall tell me Oo

I'd translate the sentence like this

"I want to enter/ride in a care that makes 'tatata'"

「タッタッタ」って車に乗ってみたいな。

I'd translate the sentence like this:

I want to enter/ride in a car that makes 'tatata'.

I don't think it's the colloquial version of ような, so I think it is みたい plus な. But in this case, I don't know what it supposes to mean.

What is this な at the end?
