Anyone interested in my golf?

I’m starting to lose my nerves! In order for my new chassis to be registered, the fenders would have to be pulled by about 2.5cm! This alone should cost about 400,-Euro (perhaps also because I want to keep the original edges or the look)! Then the cage, chassis, cathedral warehouse, license plate would have to be entered into rear bumper (for the cage I have only a material report and on the cage is not a label from the manufacturer), and that should cost around 550,-Euro again! The whole thing with a 15-year-old golf 2, which had already had a strong frontal damage! Should I do that, or do I rather get a new car?
