If you want to store it for long term, you need to keep it cool 60F and dark, cycle the battery once in a while, still getting the battery to last until it is a classic will be nearly impossible, also don't forget GM is going to build a bunch of Hummers, not so rare once production kicks up (Past Hummers do not sell as classics unless they are special). Save a C8 Z06 would be a better bet, as there will not be many, and those engines will be the last of the high revving N/A, more desirable to collectors.Last night I was thinking about car collectors and the effort that goes into properly maintaining a ICE car for decades in order to maximize its value on the collector market. My understanding is, the vehicles are rarely driven and mechanics routinely change fluids, check seals etc... to keep it in perfect working order.
So if you thought the HUMMER ED1 was going to be worth $10 million in 20+ years to some group of collectors, how would you go about maintaining the truck and preserving the battery life/power? Will it just naturally decay no matter what kind of charging/load routine you put on the system? Maybe future collectors won't care about the battery since they also won't drive it?
Sure the tech will be outdated in 20 years, but classic cars command a nestalgia premium all the time. Whether it's a Diablo or a Defender, cool cars are always cool
BTW - I'm not predicting or claiming this truck will be a collectors item. just curious how one should treat it IF they THINK it will be a collectors item.
