So I can tell you the rationale for why my sister is getting a brand new car straight after uni - she lives in a foreign country, with no family/friends around and zero car maintenance skills. So it's far easier to buy a new car on a very low monthly finance, where she knows that if anything happens she has warranty for 4 years + full assistance, no need to risk getting ripped off at some random garages. Plus the car is far far safer than some old beater you could buy for little money, which means the insurance at her young age is really cheap. I fully support that decision.
