I assume the fake rivets make the car look like it's panels are bolted straight to bare metal; therefore, naked.
Some more cars (I think) are ugly:
Nissan Silvia Varietta. The normal S15 is very pretty, but the Varietta's proportions are all weird, especially on the rear end. The fact it's N/A as well as being heavy is probably biasing my opinion, so I may get hate for this one.
Nissan S-Cargo is up next. If you don't understand the punny name, it's meant to look like a snail. And whilst it succeeds, the end result is... yeah. Came out alongside the Pao, Be-1 and the Figaro, and like all of those, is based on a K10 March/Micra.
Ford (Escort) ZX2. I've noticed a lot of late 90s American cars seem to have these weird headlight designs.
Normally, I like the 2nd gen Fiat Panda. But who was the madman that greenlit the Alessi edition? Why did they allow white hubcaps masquerading as white walls? Why did they allow bright orange seats? More importantly, why were they allowed to live?
