I REALLY dislike the sides but I did read an interesting comment. Why is everyone so fixated about fixing the door!! Yes, we do get day to day door dings but not many people get into such damage that requires significant door work. Additionally, someone else’s insurance is going to pay unless you manage to damage your own door -your need to look elsewhere for help. For significant damage, you'll prob get a new door, or as body shops are starting to do now is just replace the outer door panel, which comes with pre-stamped creases and all. This is will prob be the cheapest option over paying a body buy by the hour to recreate those hideous lines... Additionally, in the event of such damage, I'd like to think of it as an 'opportunity' to have the body guy fill in the creases and make it look like the Mazda 3.
All said, I still REALLY dislike those side creases...
