Unless you are only doing city driving, hybrids aren't that practical. You have to own one for years before they make up the extra cost. For example, a Ford Fusion hybrid is $8000 more than an equivalent regular engine Fusion. You get an average of 10 more mpg (Standard is 23 city / 33 highway; hybrid is 41 city and 36 highway; avg mileage is then approx 28 mpg standard and 38 mpg hybrid). 17.5 gallon fuel tank, so that's 175 more miles between fill-ups. That's one less fuel stop per month, maybe? If gas continues to be around $4 a gallon, each fill-up will run you $70. So each year, you save $70 per month, or $840 per year. That means it'll take 9 1/2 years before the car has paid for itself in terms of savings. That doesn't take into consideration how much higher each car payment will be (at least an extra $133 per month on a monthly car payment, 5 year plan). So actually, by driving the hybrid, you're losing $63 a month.
