these are better references the rear fender flares could be taken from the vivace rally car, the are kinda similar.
I'm kinda just elaborating on what FalloutNode said here: Although I like the idea, I don't think this car would have Sat Nav. 1. It's a Kei car, from the late 80s, and Sat Nav was an option for expensive cars(I think), and 2, the sat nav in the 80s was very different compared to this. --- Post updated --- What would the modification be for?
