I have a 2005 Mercedes-Benz A-Class. Taking golf clubs from the boot I noticed evidence of water and while washing the car I also discovered signs of paint bubbling on both side doors. Surface disruption was inside to out. The handbook states a warranty of 30 years. I went to the MB body shop and the inspection report told me I need two new doors and a boot lid. I believe MB used poor quality steel for this model/year. MB wants £3500 for corrective work with a 50 per cent contribution for me. This will not increase the value of the car or provide betterment. It was a manufacturing fault.
