unless really can not afford $3000, park donwstairs of course !
you can always find cheaper parking but need to walk, which defeat all purpose of owning a car, unless you purely use it to show off to your firend that you have a car. my firned used to do thsi when he was young. take a bus ride to get a car, coz he park somewhere free. everytime finish using the car take bus and change mtr back home. what a joke
