Easy enough question to answer, or is it? The video game's guidebook states that Vinnie is 27, HOWEVER, when you meet him in the game, he seems to say otherwise. We find out about Hojo, Gast, Lucrecia, drama, drama, drama, and ka-pow, we find out he slept in that coffin for about 30 years, which would make him... *bing!* 57!

HOWEVER... (lol) if we assume that he didn't AGE during his coffin time and the fact that he still has the body of a 27 year old... I guess it depends on your definition of "age". In the upcoming movie "Final Fantasy VII: Advent Children" which takes place two years AFTER the game ends, Vincent's age is STILL listed as 27... hm...
