How to save to avoid financing?

Hello together, in advance: the search did not give me any useful results. If a similar Fred already exists, then it was not an evil intention. Discussions, whether one should pay a car better in cash or finance there is already a lot here. Also, which types of financing are preferable to others. But I am interested rather the other side, i.e. I want to pay a car cash and put my money aside so that I can even the next – hopefully better – car I would like to know from the cash payers: – Do you consciously put a certain amount aside for your next car month after month? Or do you generally save an amount X per month and if a new car has to pay this from this pot? – How do you put the money on? Savings book is stupid, Giro account much more. Daily money account, funds or savings letters? – At what intervals do you get new or used cars, i.e. with what life span k Alculate? To the background: I will soon buy my second car bar and for me the question arises about the easiest way to do that again. Against the background I found the Fred quite interesting. Thanks already for the answers.
