Vettel was quite impressive brazil imo, the car was a midfielder in proper dry conditions with that damage but in wet conditions he was one of the fastest cars on the field which proves he has something, the crash with senna though i think was his fault but you are deluding your self if you think this was a lucky race for him.
Alonso on the otherhand, did have some cock ups in this race and really wasn't that fast till the end.
