How much I should invest if I want to purchase a Lamborghini in the coming 5 years?

this question was asked by a female participant in my recent financial literacy program.
this question was thought-provoking for me?
First of all
No question is stupid or small?
All question is the outcome of curiosity or objective.
and last but not the least
luxuries cars will be are going to be the next common cars in India in the coming years.
So moral of the whole story
if you want maximum luxuries in life then you have to do the maximum investment to buy that, not the minimum one.
Thoughts?
