Well... Sometimes her arrogance indeed hurts the feelings of her friends but they've grown accustomed to it and somehow find it cute for her to be that way.
You'd better watch the anime she's in, Mai-Otome, to discover more about her.
Cute cars...? Well... I think there are some, but I forgot what the title is. Personally I'm not really fond of cute cars so I don't have any favorite series. I'll check the animations for now and next time I'll tell you the tittles. I hope they're available to watch in YouTube, too...
Well, thank you, but then, anything you like yourself, in any way? I am curious. :3 On cat things, I did tried to look around, but I am better with full-world looking.
... and this might not be related to cats, but there is an anime entitled "Bubu Chacha". It's about a car which looks like a dog. You can also find the video in Youtube. It's a 24-episode anime.
