Fuelly is a new, free online service which helps you track your mileage. It pays attention to what kind of car you’re driving, how much you’re spending, and creates helpful charts to let you know whether your mileage is improving or declining over time.

It has great support for mobile browsers, which is exactly what I needed, since I can’t be bothered to keep a notebook and pen anywhere sensible in my car. What’s more, it also has a social networking aspect so you can invite your friends to compare mileage trends. There are also dozens of tips for improving your driving style, as well as a user discussion forum.

But I think the neatest aspect is the vehicle browser. For example, this list and graph of Toyota Priuses (Prii?), tells me that some combination of factors is forcing my mileage below the average of Fuelly members. Still, it’s a lot better than my friend’s pickup truck, who just clocked in at under 14 MPG…

I’ve come across a number of interesting websites thanks to the Wall Street Journal podcast, the Tech News Briefing, including the E-Report with Tom Dziubek and and Paul Herrmann. (Note: Tom has interviewed me three times for the E-Report.) Most recently, the podcast informed me about RepairPal, a website that helps you find a local mechanic including reviews, get your car questions answered by other community members (or by experts for a fee), and keep track of your own car’s service records.

The tool I find most interesting is a survey of the actual costs paid to have maintenance performed on any make and model. For example, I wanted to compare my recent oil and filter change for a Honda Civic with the prices paid by those living near me. I paid $25 after rebate.

Here are the results. The prices paid for an oil change range from $22 to $40 in my area, with the low end of this range paid at independent shops and the high end paid at dealerships.

The search results also include links to location information, phone numbers, and reviews for local shops. If the site can attract enough people to write reviews, this will be a handy resource. As of now, the site is new, so the list of shops is use but not as good as word of mouth for recommendations.

Lately I’ve noticed commercials for a special car buying incentive offered by Chrysler: a gas credit card that guarantees that you will pay no more than $2.99 for a gallon of gas for three years. The offer, good between now and June 2 on most Chrysler, Jeep and Dodge vehicles preys on our fear and anticipation of higher gas costs this coming summer.

But the numbers don’t work out all that well. First, in order to qualify for the $2.99 gas card, which is good for regular unleaded gasoline, diesel, or E85, you must relinquish your option to take advantage of any other purchasing incentive. Assuming the average gas price over the next three years is $3.99, and it could be lower once the political environment changes, one might save a couple hundred dollars a year. But how is this worthwhile if you have to give up a $2,000 (or more) cash back deal to qualify? A quick search of Chrysler incentives shows that dealers are offering up to $3,000 cash back. In other locations offering you can find incentives offering $5,000 cash back.

Additionally, according to the rules of this “Let’s Refuel America” incentive, your gas savings would be limited to 12,000 miles a year. After that limit, you would have to pay full price.

It makes no sense to give up a $5,000 discount in return for the possibility of saving a few hundred dollars a year. Keep in mind that three years from now, the price of gas may be much less than $2.99. You would have given up a significant incentive for very little benefit.

The perceived savings on the cost of gas is higher than the numbers reveal. Chrysler is simply seizing the opportunity to present a deal that looks nice to customers concerned about rising gas costs, but this deal is much better for the dealer than for the buyer.

If you’re concerned about gas savings and you’re in the market for a new car, opting for a vehicle with just a little more fuel efficiency compared to the Chrysler cars and trucks will be a better option for saving money on gas. Just a 3 mpg improvement will save $3,000 in the first three years, and then would continue saving money long beyond the expiration of the terms of this deal.

This is the first part of an open-ended series about major decisions that require consideration from a financial angle. The important point to note is that the financial angle is only one of many aspects that should be considered, and this fact is often ignored in some writing circles. This part pertains to purchasing a car.

When writing about personal finance, there is an expectation to center discussions around money. For example, when a personal finance writer tackles the decision to purchase a car, arguments are usually for slightly used rather than new (to save the inherent depreciation “expense” associated with driving the car off the lot), buying rather than leasing, Kelley Blue Book’s used car values, and all operating expenses (figured conveniently in Edmunds.com’s useful True Cost to Own ratings).

Personal finance writers infrequently take other, less measurable factors into account. Aspects like “fun” and “prestige” do not often rank high on writers’ list of factors effecting a decision in which money plays a large role. In fact, these human desires are sometimes ridiculed or seen as obstacles to overcome. After all, a car is simply a tool to help you move from point A to point B in a fast and safe manner. Perhaps it is the automobile industry that has convinced us that there is more to driving than a mode of transportation. Otherwise, why pay more than the cost of the car that finds the right balance between safety and affordability?

I could write a list of ten financial things a purchaser should consider before buying a car. In fact, here is that list.

1. Consider not buying a car if you already have one.
2. Consider buying a slightly used car rather than buying a new car or leasing any car.
3. Consider selecting the base model rather than one with the extra features.
4. Buy the car with the lowest True Cost to Own.
5. Get a CarFax report so you won’t be in for any maintenance surprises.
6. Negotiate the final price before discussing trade-ins or financing.
7. Research your choices for their reliability in reputable, independent sources.
8. Read the contract or agreement before you sign.
9. Don’t get the dealer’s extended warranty.
10. Don’t take on debt.

While those suggestions will help you spend no more than absolutely necessary, they are rules to be broken. I’ve broken several of them with my most recent purchase (a 2004 Honda Civic when it was new). Even though I new I could have saved some money immediately by buying a lightly used vehicle, I didn’t. I expected to be a heavy driver and I wanted as much reliability as possible for as long as possible, so for me, a new car was a better option. I also took a low-interest loan to pay for the car. I was prepared to pay cash but a very low interest rate was offered to me, so I was able to let my savings earn more interest while paying off the loan.

Consider this. New Jersey residents take an average of 32.4 minutes to get to work each day. That adds up to almost 12 full days of non-stop driving each year. That’s a lot of time to spend in one environment. I have no problem whatsoever with someone who wants to make the time spent traveling as enjoyable as possible. That enjoyment may come at a cost.

Buying a car is just one example—and not even the best example—of how major purchasing decisions can, and often should, take more than just the “bottom line” into account.

I recently explained my history of having no money and as promised, will now come clean with the mistakes I’m still making:

I’m driving the wrong car

I’ve never owned a car long enough to get it inspected. The first Jeep Cherokee was a lease, and I foolishly let them talk me into not converting the lease into a purchase. Then I couldn’t afford the new Jeep Cherokee, so I took it back and they gave me a Dodge Neon with a loan amount equal to the price of the Neon plus about $6,000. Then I crashed the Neon. That was actually okay, but only because I had Gap Insurance. Always get Gap Insurance, friends. It literally saved me from being homeless.

Years later I got a Scion xB. That thing was delicious, but I grew ever more jealous of my wife’s Prius, so I traded up and got one of my own. Sometimes I wish I hadn’t done that, because I now have a $595 monthly car payment. I know it doesn’t equal out, but it sure feels good to fill the tank only once every two weeks. I’m taking care of the Prius the way I forgot to with the Scion, and I fully intend to drive it until it won’t drive anymore. I think it’s due for inspection sometime this summer.

I love shiny electronics, and they love me

Like most geeks, I have a rapport with computers that is difficult to establish with other humans, and I tend to hoard sources of entertainment. Gadgets are an expensive hobby. It never seems that way to read about them, because the journalists get them for free. I have to remind myself of that. As an Interaction Designer, I’m always looking for a more elegant solution, for more ways to automate my life, and I can rationalize any purchase by telling myself that exposure to these things will help me in my career.

That’s how I managed to “buy” an iPhone. But as you’ve guessed, I put it on a credit card. Nearly everything I own that is worth something was put on a credit card. But I’m committed to stopping that. As of this writing, I have just over $7,000 in credit card debt, which I expect to have paid off within the next 16 months.

So, I have to keep telling myself that I don’t literally need an Apple TV, or a 1 Terabyte external hard drive. When I force myself to think about it, there’s nothing in the entertainment compartment of my lifestyle that is actually broken. It’s just not perfectly elegant, and for right now, because other things are broken, that’ll have to do.

I don’t sell enough of my stuff

When I upgraded my iBook to a new MacBook last May (see previous problem with shiny electronics), only about $1,000 of the purchase went on a credit card, ‘cause I managed to sell the iBook on eBay for about $600. I’ve got a boatload of unused electronics that I could be selling, but it seems like such an effort to even bother writing descriptions for them. If you have any advice for doing this more easily, I’m happy to hear it.

The interest rates are too high

On both our cars and the house, our interest rates are higher than they could be. At the time, of course, it was the best we could do. I should mention at this point that my wife’s credit history is slightly worse than mine, and until we started making mortgage payments, my FICO score was on the positive end of “Fair”. Naturally, the FICO isn’t the only thing that creditors look at, but mine has increased roughly 70 points in the last year. One of these days, I should really look into refinancing at least one of the cars.

It’s somewhat painful to admit mistakes, especially when they’re ongoing and not likely to change anytime soon. But if you don’t acknowledge there’s a problem, the likelihood of it being fixed goes down to zero. So, it’s a start.
