Under $ 20 K ? You could get a brand new Hyundai SantaFe SUV which
is a 'sport' utility vehicle ! Actually, i have a 2002 and its a huge
amount of value for the money. 100 k. warranty. V6 for plenty of power,
handles nice, good sound system.
If its a fast sports car you want, id consider a C4 around a 1989
.. which will give you about $8-10 k. left over for gasoline .
