Hi everyone, I need advice about an approved used c220 i bought a month ago. I found the car in excellent condition and ignored some miniscule spots on the windscreen considering it as part and parcel of the wear and tear on a 2 year old car. However when I was driving home from work a week ago right before the sun sets and the light hits you in the face if you are driving towards it, the visibility became so bad that I had to stop the car and wait for the sun to go down completely. It turned out that those little spots were actually tiny chips on the windscreen and the light was spreading after hitting them! i took the car back to the dealer at Mercedes Shrewsbury and after inspection they have decided to replace the windscreen. My question is whether this will decrease the value of the car and if so is the dealer liable to pay me back the difference? If not then do they ATLEAST owe me an apology which has not been forthcoming until now. Many many thanks!
