hello, I use this forum today for the first time and would be happy about stimulating contributions. we have bought a twingo, bj. 1999, with 109000 km of running power. now we have learned that the timing belt has to be changed. an offer of the renaultwerkstatt has clouded the joy of buying. the change of timing belts, water pump, running belts for the air conditioning system would cost 620,- €. can tell me if the offer is good, normal or overpriced. best thanks in advance for your contributions.
