Do not bring a car to Amsterdam unless strictly necessary. Parking is very expensive and is universal (almost everybody pays for it)
Rates are pretty close to 3 euros an hour (nasty!)
There are tricks, like parking in places to the north, of the city or near the Central Station, where parking is cheaper.
If you forget to feed the parking meter, they will clamp your car. It is kind of hard to drive it that way......Leave your Ferrari at home.
Unique Suggestions: If you have to do it anyways........Feed the meter religiously........don't forget!
As already said, parking in Amsterdam is a real pain in the a$$. There are hardly any free places, and if you're lucky to find a legal place to park your car, you'll be poor when you return after some shopping, and not because you bought so much! ;-)
Unique Suggestions: If you're smart, you take your car to Diemen (though there are more places suitable), and from there take the train (to Amsterdam Central Station - takes 10 minutes), or the tram (I prefer that option, because you get to see more of the city). Line 9 starts/ends in Diemen (centre, 'meubelboulevard'), and within 20 minutes you'll be in the center of Amsterdam.
When you're in Diemen, make sure that your car is parked correctly, and in a place that's for free, and looks safe.
Trams/Trains run from the early morning (something like 6AM) till midnight.
