I don't need that because I currently travel three times a year with the TR60. But since this statement comes directly from the bank, it should be accepted. This is what the next page looks like if you continue in the app. I might order it sometime to look at it.
Did this about 2 months ago. As already described here, you need a registration form, national and international driving license, and medical certificate. Costs per driver's license group (car and motorcycle for example) 500 at immigration, 100 for the medical certificate (but someone else can get it for you, you just need the passport copy) and around 350 at the traffic office (for passport photo etc). In the worst Ask some questions or watch a video regarding traffic rules.
For the 60 day visa you don't need any proof of income (at least in Austria). The only question is, do you earn up to 20,000, from 20,000 to 40,000 and so on. No exact information necessary.
