for people with '98 + cars... here's a cool site that caculates it for you by gas prices regional average, make, model, and year of your car, as well as starting location and destination.

i would NEVER consider driving my 240 that far. it'd be so uncomfy, loud, boring (esp since the radio just got stolen), so dreadful.
word of advice: while it may only cost around $280 in gas you also should factor in a "incase-shit-happens" budget. seriously.
