Twingo – again TÜV or away with it?

hi, I have n 1995 ́er, 40KW, 1,2 L twingo as a winter car. tuv still until 03/2013. ran before in the family and the clutch was renewed in 2012. engine runs great, jumps ( thanks to new OT encoder) again great. transmission switches very well. but: paint condition in short: terrible. everywhere scratcher. beautiful bump in the koti left hood goes after rempler only with nem screwdriver – closed slightly bent. left headlight has to be replaced – but halting is broken therefore not more adjustable. long talk in short: optically an ab**** box, but from my experience one probably brings about 200-300 euro through the tuv. (lights, possibly what about the brakes in front and the chassis parts) I already screw a lot myself but the question is: is it worth the ? 300 parts + 80 tuv -> then I would have to get a minimum of 400 better 500 for the box. pays someone ? make, throw away or possibly slaughter so motor and gearbox ? mfg loomi
