Buying a DC2R what to look for?

[cusco echo]

ok i did the search, just got a few more question:
is the 2000 and the 2001 model same or they have some different?
if the car is serviced every 10ks instead of every 5k, is it still ok? or should i walk away?
would the car have a lot of different in power and speed, if i had 3 people in the car with ac on, compare to only 2 people in car without ac?
how do i buy the car if there is still finance owning on it?
if there is rust on the brake calipa (spelling) is it normal, rust is not on brake disc, its on the calipa?
is the black colour metallic or solid black?
