So people are always saying how expensive it is to fill up, but I've not really heard any real numbers. My wife took a look at our account this month and figured out that between gas and tolls we spend about $350 - $400/month. Keep in mind that we have two cars; an '01 Mazda Protoge which I commute to work in and a '98 Volvo XC which my wife drives around town (she doesn't work). I should add that I commute about 20 miles each way to and from work. Only thing I can figure to cut cost is to buy a hybrid; I already get high gas mileage in the little Protoge. There sure as **** nothing I can do to reduce the toll costs I incur on a daily basis. Sucks. What about you guys, what's the monthly damage?
