Camaro 1999 Purchase as daily vehicle Pro/Contra

Hello toammen, I am 20 years old and would like to buy a car. Which I have directly caught my eye and I have only difficulty getting out of my mind is the Camaro 4gen. from 1999. Have you had good/bad experience? share with me. I have a viewing appointment on 17.8. What is 1 of the biggest problems of my knowledge, is the consumption. How many kilometers did you manage with a 59L tank filling? How much does a tank filling cost? Does E5 Super? a few informations about the vehicle: 5750€ V6 193PS 66000 KM Automatic Alternatively, I’ll be looking at an A3 1.5Tfsi S line soon: 16500€ 2018 99000km 150Ps Thanks in advance.
