Lupo GTI – Questions before purchase

Hello am new here in the forum. Have already read around a little, however, my questions about the Lupo GTI are not answered, or I am too stupid with the search function…. :/ Have to buy a used GTI before me. Now to my questions: – What experiences are there for the 5-speed transmission. Is it in some form “bader” than the 6-speed transmission? – What about the sound of the “gamma” system or the boxes. Is it a rather bad or rather good standard system? – Which Werkas The car I’m interested in has 72t km down. What other “weaknesses” does the Lupo GTI have to offer? What damage can be expected in the foreseeable future? Thanks already, if jmd still has tips to buy —> please write me or send me links
