Another possibility, just thinking out loud: Gas goes to $10/gallon and yeah, in the short term, maybe these cars don't hold their value like I believe they will. However, $10/gallon gas would surely hasten the move towards EVs .... and then this truly is the last of a dying breed. In 10-20 years values recover and then some.
Having said all that, I've never leased a vehicle so I don't know the rules. If the lease entitles you to buy the car at the residual value (YOU have the option at that pre-determined price), then I can see how leasing wouldn't be so bad, either. Basically, if you make a good vehicle choice then it doesn't matter so much whether you buy or lease.
