besides super-carros I don't know any actualized site, anyway you should check directly the cars, I recentrly purchased my fisrt car here and was funny to know that when they say "excellent conditions", "as new", como nuevo!, nitido! only RD$400k! (for instance) , it usually means semi-junk by euro-usa standars, but if the same car is really "as new", then the same model is 500k
, so reading the adds can be misleading
also thanks to leonel all the cars are more expenxive now,
