Seoul: Bus and subways are $1/ride, you can combine a string of bus and subway rides together in certain ways on one fare, because bus and subway stops are often convenient for some and not for others. Two types of taxis, regular and deluxe, regular meters drop at a little over $2, deluxe a little under $4, I don't know the system but it's pretty cheap. You can go from one side of the city to the other laterally or vertically for about $10, diagonally corner to corner for about $20, and Seoul is pretty sprawling. A normal ride I take is usually about $5 though. Cars: price to purchase are double that in America, gas is double the US price, cramped parking (that's like where you have to fold in your mirrors, and sometimes climb through the other side to get out) is about $300/month for a spot, so double that if you work somewhere and need a parking spot at work too. You can get better spots if you lay down a big deposit, like $2K, and you can get it refunded to you when you're done. Landowner will use the money to make more money on their own. Valet and streetside parking costs are similar to other cities. None are bad, but driving is pretty insane here and there's nowhere to open a car up, so while car ownership here is completely unnecessary and cars can be bought for fun purposes here, I don't know how much you can enjoy them. My friend took me for a ride in his modified SL63 the other day, we were blasting the big bridges and tunnels, but apart from that it was more like stoplight racing, more braking than accelerating; there's barely any room to open cars like that up. That said, having a nice car over here is a special thing, you definitely cruise for girls if you have a nice car.
