Honestly I think the 4xe is way better than any of the EV's out there. At least you can run on gas when you travel longer distances. The infrastructure isn't readily available to "fill up" an EV when the batteries drain at the end of their range. The cost and time required to fully charge makes EV's impractical for just about anything except commuting in town. The overall cost of EV's and the future battery replacement is sounding astronomical and IMO effectively makes them not feasible for 80% of Americans.
A plug-in hybrid on the other hand is at least relatively practical even if it is more costly.
That said I am sticking with my gas powered JT until they want to do an even swap for a new 4xe, because that is the only way I would consider one.
My guess is most of the 2024 "improvements" will be cosmetic.
