I bought myself an expensive car, and I love it. How about that?
Is this true? Really true? Why did you buy an expensive car?
I want to impress girls with it
I it is okay to buy an expensive car and want to splurge on yourself. But you should not buy it to impress the girls with. It is kind of shallow to do so.
Whatever. I got what I want.
You can do this if you have money to and want a certain thing out of life. No one can stop you. Just have good clean fun with it and no harm done.
