$20,000/year? How many miles are you driving?
In my case, I average about 7,000 miles per year on my 4Runner (I live only a few miles from work), which works out to about $2500/year for gas. Thats based on 7,000 miles @ 14 mpg. 500 gallons of gas purchased in a year @ $5/gallon.
But even if I drove twice as much (which is more than the national average), I would still only pay $5000/year for gas. I would have to drive about 28,000 miles per year before I would be paying $20,000 for gas at $5/gallon!
The reality of it all is that I\'m already paying around $3/gallon for gas, so even if it goes up to $5/gallon, it\'s only an extra $1,000 per year out of my pocket, which is not nearly enough to make me even consider getting rid of my 4Runner
