It's hard to be precise because taxes differ between states in
the USA.  Also, prices are negotiable and can vary widely between
dealerships even in the same state.  I am not knowledgeable about
how this compares to selling practices in European countries.
Also, there are lots of manufacturer's incentives (rebates, finance
offers, etc.) to boost sales from time to time.

If I remember correctly the invoice price of my 2000 Focus SE
wagon (estate) was just under $18 000 USD, with 2.0l Zetec-E,
antilock brakes, A/C, cruise control, side air bags, etc.  I
haven't been keeping up but I imagine the market price for
similarly equipped Focuses has come down since then.

I follow the uk.rec.motorcycles newsgroup where it is a generally
accepted truism that in retail prices of many goods there is a
correspondence of about $1 = £1, e.g., something that costs $100
in the US will cost approximately £100 in the UK, despite the
fact that the pound is now close to $2.00 USD.

http://www.carsdirect.com will give you an offer for a given car in
the US.  You have to give a 5 digit US ZIP (postal) code because
prices and availability vary regionally.

http://www.edmunds.com will give what they say is "true market value"
for a given car in the US.  Again, the ZIP code is needed.

No, they don't. Prices in Holland are at least as high.

The prices in Denmark are the highest of all EU countries. But that is only
because of taxes. So in order to be affordable by any means, the base price
is among the lowest in Denmark of all European countries. Base price may
differ 2-4000 Euro between Sweden and Denmark, without tax. And, if you
export from Denmark to another country, most of these taxes are deductible.
