i have had a 1.7sdi arosa and never had a problem it got driven hard and seemed to drive very well cruised at more 70mph+ with out giving me a headache with 3 people in it as well the 1.7 sdi engine isnt regarded as a good engine and with the climate we are in i think its great cheap to run with no fuss only had to replace a wheel bearing in the year i owned it your gonna get problems with all cars no matter how old or new its one of the joys of motoring
