Like almost everything, of course 'it depends'.
And I don't know that much about cars in that price range, but if I won a raffle draw, and had 3 seconds to choose A or B, I'd choose B (the Porsche). I would just think that a Porsche carries more cachet than a Corvette.
Of course if I actually did win either in a raffle, I'd probably sell either after a month or so - I think that's all I'd need to get it out of my system.
EDIT/ADD - that's kinda funny, the Title and the OP said nothing about a raffle - I just threw that in as I wasn't sure what the situation was where I'd be choosing between these cars, I submitted, then went to vote for the Porsche. It wasn't until after I voted that I saw that the poll itself has a separate title, and that has the raffle scenario in it.
Further edit - DW would definitely answer "the yellow one", but I see that's not a poll option (she wouldn't care who made it).
