I drank my car's dollar value in two evenings. Are the old vintage first growths Bordeaux tasty?

We drank almost 20,000 dollars worth of wine in two evenings. The five first growths Bordeaux, les premiers grands crus de Bordeaux, are they really tasty once they get aged? Chateau Margaux, Chateau Haut-Brion, Chateau Mouton Rotschild, Chateau Lafite Rotschild, Chateau Latour, are they worth the money?
