in 10 years, will gasoline be available for purchase at all? if a large population of consumers is not willing to pay $10/gallon then the gasoline economy will collapse (and presumably be replaced with electricity or CNG). you may be willing to pay $20 or $30/gallon, but your "classic sky" wont be worth much if it needs to be driven 160 miles to one of 40 "historical" gas stations in the USA just to fill it up.

of course i am playing "chicken little" here, but who could have imagined $4/gallon gasoline and the collapse of the SUV market would happen so suddenly?

on that note... has anyone looked into converting either of the sky engines to CNG? what would be the cost, fuel economy, performance implications? CNG may be the best way to guarantee the future value of your "classic".
