Dear Driving for Dollars,
I inherited some mutual funds that are luckily earning good money. I want to buy a car with good gas mileage since gas prices are predicted to keep rising. Should I cash in some of those funds and pay cash for a new car, or should I take out a small-interest car loan?

Dear Confused,
There are many ways to approach your decision, but I would suggest you look at the average interest these mutual funds are earning and compare that to the interest rate you would qualify for if you were to get a new car loan. If the mutual funds are likely to earn you more than the interest rate you would pay, it makes more sense to get the car loan and keep the mutual funds intact.

You also indicate that you are interested in buying a new car because of a predicted rise in gas prices. If that is your only reason, then you may want to rethink your purchase entirely. According to the federal Energy Information Administration, there's only about a 35% chance that regular gasoline could reach $3.50 per gallon on national average this summer -- and only a 10% chance it could reach $4 on average. The current national average is $3.14 per gallon of regular gasoline. Instead, you may want to focus on finding cheaper gas or take gas-saving measures offered in this Bankrate story.
