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

The only thing I can think of is to keep it in a garage with a cover over it and keep the garage temperature controlled as well.

Ok, so drain all the fluids…check. Put some sort of rubber conditioner on the rubber seals…

maybe a special humidity controlled bag? Maybe have the engine professionally removed and stored nearby like the heart of tutankamun next to the mummy?

I was thinking maybe you could try to get Nissan to help from before it was mfg.ed…

Most car collectors would want the car to have always been in “resale” condition.

I would say yes climate controlled garage, keep the engine in it!!

Also it doesnt make the car worth any less to keep the fluids in it and crank it once a month.
You dont even have to drive it anywhere but at least keep it in running order.

I dont even know lambo or ferrari owners who would go thru all the trouble you are talking about :)

From what I’ve heard/seen, it’s better to keep the engine fluid-filled and run it every once in a while rather than keeping it empty and not running it for 30 years.

I would also keep the room climate/humidity controlled, and have air purifiers to keep excess dust from building up.

I’d also wash and wax it once in a while to keep everything moist and nice.
