My opinion on these hasn't changed. It's creative and interesting, and when they're well done, they're very pretty. But the illusion lasts up to the point where you realise what it actually is. Sometimes that's when you start it, and sometimes that's when you get in it and it has a standard interior... but either way it's completely destroyed when the wheels start turning.
I won't criticize someone for doing this well, because I respect the skill, even if I think the donor car is prettier than what was made from it.
I happily drive a Cougar. I wouldn't want to drive a fake Ferrari and wait for people to call me out on it.
