I think any vehicle can be prettied-up or improved.
Personally, the first half dozen years I owned my 1st generation, I had a lot of people take a second glance, and many times come up to me in the parking lot and compliment my vehicle. A few discussions on my add-ons.
I made mine look off-road.
Some people don’t know what I drive, but still people at stop lights and on the street give approving responses.
I think the funniest one I heard was when a young African American lady said. “ That’s mothe*%#*^#¥ Ghostbusters”!
Anyways, I get my fair share of compliments and ugly was never one of them.
I am sure any vehicle can be ugly when you don’t take pride in it; and just not caring for it which in turn may result in it looking crappy.
