Part Financing from the car as a valuable investment Meaningful?

Good day I play with the idea of buying a car as a 2nd car as a value investment/summer. Unfortunately, I had an accident with my actual summer car about 3 months ago. I am 20 years old and earn about 220€ net still live with my parents and have saved a good 7,500€. Now I stumbled on an ad which sounds very tempting a Golf IV R32 1st hand and 77,000km for 20,000€. But should take on a financing and w don’t know if it’s worth buying the car as a value investment/summer car. I have a 1.9 tdi to work which is really cheap. Now what’s your opinion? Is that maybe only the teens senseless or worth something?
