This sentence always works. En España se conduce un coche. En Sudamerica se maneja un carro. Saludos

This is hard to explain, in south america, in Chile the people "eat" the last "s" of the word, in Argentina they pronounce different the "ll" and "y" many people say that Mexican spanish in the neutral spanish, just with practice you'll be able of different the accents this is Spanish from Spain http://www.youtube.com/watch?v=OH1Gx99EK9w Many accents http://www.youtube.com/watch?v=aU4D2nKrRmM&feature=related

It's very difficult to know it, but you may have some tips. In Chile, there's so many accents depending on the area. The popular speaking it's very different from the right speaking chilean spanish. When you're talking with your friends it's very usual to deform words. For example, "haces" (to be) changes to "haci". This spanish is only in Chile. An argentian may put the accent at the end, "hacés". I also think mexican spanish is like neutral, but you can know easily when an mexican is talking because of their slang. But to me, peruvian spanish is the easier to understand. And in Spain pronounce exaggeratedly the "sssssss", but the really difficult ones are from central america and caribbean.

ok I think it's a little easier if you know the accents.. in every country and in every part of the world people has a different accent.. I mean entonation!.. so at the end it's a little difficult .
