I’m baffled

Hello first of all I’m a newcomer here in the forum and I also have a few questions. first of all about the situation, I’m just about to buy a new car, best of all, ami. like probably many other us beginners in my old age, I want to have a nice but inexpensive car. I’ve already gucked into one or the other ami and also searched the well-known insurances online but none of the heinis offers such vehicles in their database. so my question 1. which insurance insurance amis cheap 2. how does that relate to the taxes and the insurance with oldtimer and not oldtimer 3. where do I get cheap reasonable (solider ramen, etc.) ami further questions certainly follow thx already for the help until then
