It's funny...once you own a gas guzzler, it doesn't make much sense to dump it and lose $3 or $4k over the sake of $200 more in fuel bills for the year.
But people are doing it...and other people are picking up bargains.
(albeit at some environmental cost).
I just got back from Thailand. Regular was $1.80/gallon and premium $2.00/gallon in US units. Disel was about $1.55. It had went up about 6 cent/gallon while I was there.
The lowest I saw it here in Northern California near Sacramento this morning was $2.05 for regular and $2.25 for premium.
