As Topper said, The silver one has been accident repaired. It could be graded R/1 for modified and repaired. But it's up to the guy setting the grades I suppose if he thinks it's a "modified" item or not
By looking at the auction sheet the silver one has alot of panels exchanged.
Both front fenders
hood
passenger door
passenger side side skirt.
There is some remarks about the panel changes in the sheet, but I can't read japanese so I have no idea what it's saying.
Considering allt the panel exchanges, It might have been in a pretty big crash. But I'm only speculating here.
It has a higher interior grading compared to the purple one though
Edit: BjornE, Do you have access to see the auction sheet?
If not I can supply you with a link and login so you can have a look for yourself.
