How do you go about preserving a dream car even before day one?

So, let’s pretend I saved up all my pennies and bought a GT-R from Nissan. Not to drive it. Ha, how rediculous. I want to save it of course just like I saved all that money!

So, industrial sized drum of cosmoline? Ideally a normal two car garage would be the storage site, with the hopes of returning it to the market place in 30 years.

I know…in 30 years we’ll have flying, electric/wind powered hybrid, automated, X-wings…...

but lets pretend that the car will appreciate if preserved well.

Thanks
