Might go buy a new Challenger tomorrow

$2300 in fuel saving ain't much when compared to possible increased payments and insurance and cost of ownership. Not sure current mpg vs new mpg.
50 miles per day in a truck getting 10 mpg is 110 gals per month. At $3.50/gal that’s $385 per month. Get a car averaging 20 mpg and you save $192 every month. I would call saving $2300 a year in fuel costs pretty substantial.
