If you're looking for success, recognition, or gratification at a car show, you'll likely come home empty handed, regardless of whether you're driving a "real" supercar or a clone.
If you're upset your real Supercar got beat by a clone at a show, then you should likely go home and shine on your Supercar until it's as fluffy as the clone, or reconsider what the $4 trophy the clone took home instead, really means to you.
I think everyone is entitled to do as they please with their cars, restore/not restore them, clone them into something they weren't etc. etc.
The important thing is remembering why you're doing it, for love, money, or the pursuit of a trophy, don't lose sight of what you're true intentions are and you won't likely be disappointed.
