How to accept your guilty pleasure as a frugal person?

Hi,

I have been a frugal person since my childhood. Always bought the item that has the best value proposition. Never splurged on anything except food. Now finally the day has come when I buy that one thing that I loved to own ever since I was a kid. A car!! So there are two cars. Completely polar opposite.

A VW Virtus @ 18L and a Honda Amaze @ 12L. The heart wants a VW Virtus as its the most fun to drive sedan under 20L. But my frugal mind wants an Amaze as it basically ticks about all the boxes except the fun to drive part and is almost 6L cheaper. I did book a Virtus as a impulsive decision as I just enjoyed the TD (That was like the 4th car I did TD that day and the first one I literally enjoyed.) The delivery is still like 2 months away and I am having second thoughts. I am like the 6L saved over a period of 4 years could essentially become a major part for the down-payment of my house. Also since I'll only use it as a weekend drive, I am literally having guilty feeling of spending. This all started because I always wanted to own a gaming laptop and play games on it. But could never make up the courage to ask my dad as a college student. So when I saved enough I went and bought one. Thanks to my busy work schedule... I hardly play now for like 2-3 hrs a week on an average. Am feeling guilty like I'll be spending 18L on something which I'll use only for the weekend. Isn't it too much for a frugal person? I can afford upto 20L based on my current pay. So money is not the main concern. It's my mindset.

If you were in my position what would you do? Would you buy the car to satisfy the inner child in you? Or would you buy the car which makes financially more sense while comprising only on some aspects (Fun to drive)?

Edit: The laptop story supports to be frugal while in contrary my bike purchase wants me to splurge. I kind of regretted my old bike for lack of power. Enjoy the new one. If I had got the new one on the first attempt, I wouldn't have got a second bike.
