Help with the purchase/selection of used cars

Hi I hope I have chosen the right forum, there was unfortunately no general… I am now 19 and I am just finished with the school and want to buy now n car and am just working for it ^^ From the 1.9. then Zivi starts… But I have no idea what kind of car I should take and what to look for etc. I will not drive more than 1000km per month because of civil service etc… in time I will have about 400 € per month available, of which höc Is there no diesel or n petrol better? Actually, n petroler because at so few kilometers the cheaper diesel is not worth compared to the high taxes or? I write down some data on how the car should be, maybe someone can help me – should not cost more than 2000 euros – no high taxes – relatively low consumption (under 8l if possible) – at least be half tidy (look, condition etc) – not a be negligent for repairs – reliable Have looked around at mobile.de, but have no plan at all which model or which manufacturer I should take… I would have thought of VW, because the vehicles are usually quite robust, but I was told that the tax etc. are too expensive :/ oh yes, would not be bad if he had at least a few hp and pulls something *g* but that is probably not possible with the money so rather incidental would me over totwor MfG Johannes
