i am 17 and looking to get a mazda speed3 that is around 8,000-13,000. But im not really fimiliar with them and wondering if there are any main problems i need to be aware of and also if you have to replace parts on it a lot because my dad wont let me get one if you keep having to replace and fix things on it.
