Just saw a sticker from a 78 F-car where they figured the yearly fuel costs based on a price of $0.70 a gallon. If you figure a 78 308 window sticker at around $41,000 then it would be around $120,000 today adjusted for inflation. That $.70 gas works out to just over $2.00 a gallon which is exactly what I paid Saturday when I filled up!! Interesting!!
