Why are do many people buying cars?

I just went to a local Ford dealership to get my key fixed and it was busy, and most people there were buying or leasing a new car. I'm pretty sure those people don't have the money to make that kind of investment so why are they causing themselves more debt that people like me have to take care of in the end?

Should i buy second hand ford ikon?

Ford Ikon 1 year old good condition
Price 1 Lakh
Should i consider buying it?

Added (1). ford ikon was discontinued this year in my country because of BS4 norms
