6 CD changer? Isn't that somewhat over the top?
I don't know about the US, but here it is cheaper to buy the car and then add all those add-ons like leather and good radio. That's because when you buy a car, everything is with 50 % 'luxury'tax. What basically means that the the Dutch government is trying to suck even more money out of the people. But if you buy it afterwards it 'only' has 19% tax on it. For the Mercedes my Dad has bought it saves about 1000 EUR, so I might check that out.
But then the US probably has a completely different system.
