Ford Mustang Shelby GT 500

HI, so in brief I got a Ford Mustang Shelby inherited as mentioned above, and I would like to know if I can use it as my car or entertain it !? At the moment I drive an old Opel Corsa which will definitely not survive the next TüV! So I’m a trainee with a fixture and earn 1,100€ net per month. Could I hold the Mustang with about 500-max. 700€? There are many memories about it….that’s why I want to keep it. He just has 30,000km. I would take him daily to work or school about 60km daily and at We mal vllt for smaller trips. So I would be able to pay fuel, insurance and etc. with my budget or does he blow it extremely? I heard that he is not so expensive in maintenance and the engine with good care far beyond the 200,000km, which suggests to keep him. By the way 19 years driving license for 1 year and insurance runs on the grandma who has 35% LG
