Buying first car in Japan

I'm a Brazilian who recently just got their license in Japan and I'm willing to buy a car.

My income is scholarship + baito, so it goes to around 22万 after taxes, so I'm thinking about an older kei car, more specifically a kei truck. I'm a collector and I enjoy CRTs a lot, so I think it would be great for going to the hard off.

I enjoy driving MT, so I'm thinking on getting an MT car. I drove both automatics and manuals in Brazil and hated the ATs, so I am positive I want an MT.

Some other thing I am a little unsure of: How viable is a kei truck to travel to another city (around 170km)?

Thanks 🙂
