What do u think about not having personal car?

I have worked for more than 10 years
I try to save my money and spend a little just for paying taxi, buy cloths and my favourite foods
I go to work by metro and taxi and it’s more comfortable and economic than personal car
I also have gone on many good trips abroad ( luxury and 5 star hotels)
I plan to be retired at 45 years old and at that time I want to buy a Mercedes Benz and a small house abroad to go there one month each year
Is my plan a good idea? What’s better for me to do in your idea?
If you were in my shoes, would you buy a personal car right now?
