Part financing from the car as a value situation?

Good day

I play with the thought as 2.Car to buy a car as an investment/summer.Since I unfortunately had an accident with my actual summer car about 3 months ago, I miss something very much.

I am 20 years old and deserve about € 2,200 net still live with my parents and saved a good € 7,500.Now I stumbled into an advertisement that sounds very tempting to a Golf IV R32 1.Hand and 77.000km

For 20.000 €.To do this, however, would have to take a financing and do not know if it is worth buying the car as a value system/summer car.

As a car, I have a 1.9er TDI that is really cheap costs.

Now what is your opinion?Is that perhaps only the young people unreasonable or is it worth it?

Warm greetings
