I have BMW 518d Reg 141. Last year, one of the front headlights was replaced due to water condensation which costed me EUR 1,500 and now this year the other front headlight needs replacement for the same reason and now it is costing me EUR 2,500. The car runs perfectly fine, however since the car is 10 years old now, is it worth spending this much on the car and keep the car for few more years and hoping that I may not get higher maintenance costs in the coming years or is it right time to exchange it with another car? Thanks
