Hello, just bought an Audi a3 58 plate, with few body defects. There is quite a nasty dent on one of the sills (picture below), I wanted to ask maybe someone has ever been taking out the inside part of Audi a3(where the carpet is on passenger side) and know if I could access somehow the inside of the sill to push it out back? Thank you very much, can't wait for your responses.
