I saw gas last night for $1.95 a gallon. When gas was $4 a gallon a couple of months ago, people were rushing to dump their trucks and SUV’s to get more efficient vehicles. So has the opposite happened now that gas is cheap again? Since car shopping in May, I’ve been on a bunch of car dealers’ e-mail lists. I got an e-mail this week from a Toyota dealer saying they are having a Prius Clearance Event, a “blow out” sale on 25 cars, selling them at dealer invoice cost.
