I think it's an enormous challenge and it must be very satisfying to build. I know I would have enjoyed it very much.
Said that... buying a ready-made one is like buying a built Lego kit... totally pointless
And I suppose that those who build these 'clone' cars have the same issue as avid Lego builders - once they have finished enjoying their creation, what do you do with it....?
I have better things to spend my money on, so why not just buy a fake one and save your money. I can afford to buy a real one, just prefer wearing a fake......honestly
If you pay £50 for a clone of a £5,000 watch then you have paid 1% and a small amount at that - so even if you have nothing of value to show for your fifty quid you can call still it 'good fun'.
If you pay £20k for a clone of a £130k car then you have paid a staggering 15% and an eye-watering amount in absolute terms - especially given that you have absolutely nothing of value to show for it.... not fun
This reminded me of what a rather 'large' friend of mine used to do in such situations.... he'd point at his large belly and say: "You have no idea much this cost me... but does it have any value?'
Many people find it difficult to accept that just because they spent a lot of time and money on something does not mean it has any value
