Statements should be factual and not misleading.
I think it's a matter of how much they want to learn and how much they care about the subject matter, be it cars, learning Japanese, or anything else.
Most girls just want to get into cars and learn stuff because guys dig chicks that know their s*** but in actuality, they have no genuine interest. So when you're heart isn't into it, you're not going to try hard to understand it.
I'm not going to pretend I know everything, but I can do my own maintenance and I appreciate nice cars. If I have a guy to handle the dirty technical stuff, then hey, more power to me, right? Why do for yourself, what you can get others to do for you - for free?
Japanese is actually a fairly easy language to learn BTW. You should give it a shot.
