Super Plus? / Questions before buying…

Hello all, yes – I’m new here … I want to get a used “TT Roadster” soon – so I came across you some time ago! It gets serious: Now I’m not sure at the moment whether I should set myself on the 150 HP or the 180 HP. Quattro I have meanwhile already deleted from the wish list for cost reasons and in favor of the larger trunk. so stay 150 HP -> Super petrol, lower consumption, apparently lower maintenance 180 HP (Front) -> Super PLUS petrol (higher consumption and maintenance) – added value? Important questions concern me: – MUST the 180hp model “Super PLUS” be filled? (or doesn’t it have to be at all? – As with the “small” – How noticeable is the difference in maintenance/insurance? – Does one still have a “splashy” car with 150hp (I would say I drive less top speed on the highway – but would like to progress on country roads, over mountain and valley, “flott” – well – just have a bit of fun while driving…) If the TTR with 150hp should not be considered as undermotorized, but instead conveys the fun, because of which one buys it at all, he would possibly be a concession to reason… ? 150 or 180 – this is the question… …yes – you have to make such problems yourself… 😉 In advance thank you for your help!!!
