Ferrari F50?
No...
A car under cover is not that easy at all! It is indeed quite obscure and that's why it got this level straight away.
That's what I thought too but if it had turned out to be right and I hadn't asked I would have been cross..!
But as you say a car under a cover could be one of very many cars and there is really no clue, so one has to start somewhere..
So, is it Italian?
