Who Should Get The New Car: Husband Or Wife?

I got a text message from a friend asking for advice on an interesting situation. The husband and wife have one newish car and one oldish car.

The husband only needs to drive about 10-15 miles a day, while the wife drives 60 miles a day to and from work.

Which car should they use for each of their commutes?

First, we have to make a few assumptions:

  • The old car only has at most, another 45,000 miles on it. You never know when a car will die, but the expectation is that it won’t live longer than that.
  • The husband is in medical school and once he graduates in 3-4 years, their income will increase.

Drive The Older Car Long Distances

If they drive the older car 60 miles a day, or around 15,000 miles, year, they would likely need to replace the car in the next few years.

Their plan is to drive their cars into the ground until they become unreasonable to maintain. They’ll put in some money for basic maintenance if it means keeping the vehicles up and running, but significant maintenance would force them to discuss whether it’s worth it to pay to have it fixed (and hope that it lasts long enough for the repair to be worth it) or to sell it for whatever it’s worth and buy a new (or more likely, a used car).

One pro of going this route is that if the old car dies in the next few years, they’d be able to get a new car, which everyone likes the feeling of.

Drive The Newer Car Long Distances

By driving the newer car 60 miles a day, the couple can ensure that they won’t need to replace the older car for the next several years. In fact, by only driving it 15 miles a day, it would last through medical school and then some (depending on how the husband’s commute changes over the years).

However, the downside here is that the new car will quickly become not that new of a car. You’ll have one old car and one car with normal use that will by that time, be outside of its warranty period.

Calculating Total Worth

One way of looking at this is from a purely mathematical standpoint. Let’s say the new car is worth $15,000 and the old car is worth $5,000 right now.

If the new car gets driven 45,000 more miles over the next 3 years, it would be worth about $8,000, while the older car would be worth maybe $3,500, so the total loss of value would be $8,500 over 3 years.

If the old car gets driven 45,000 miles over the next 3 years, it would be nearly worth maybe $1,000. If the new one drove the short commute, it would be worth $13,000 after the same time period. The total loss of value in this situation is $6,000.

From this standpoint, it makes more sense to drive the old car first because driving 45,000 on the old car reduces the total value of the cars less than putting 45,000 on the newer car would.

Their Solution

I recommended that for their situation, they should drive the new car more because they’ll be in a significantly better financial situation once the husband graduates medical school and having to shell out thousands of dollars for a new or used car won’t affect their finances as much as if they had to replace a car in the next few years.

Ultimately, they made the same decision. Whether it’s because of the argument I made or because the wife was the one with the long commute and wanted her way, we’ll never know.

What would you do in this situation?

  1. I don’t consider the “oldish” car that old. 45,000 miles on it is what? A little over 70,000 km.

    I suppose in this situation I would bank on the newer car being more reliable for the longer haul, and being able to take the wear-and-tear. If they’re going to drive both into the ground then drive the newest one for the longer commute.

  2. FI Pilgrim says:

    I would rather my wife drive the newer car, because at that distance I’d be afraid that her car would be the more likely to break down. So for safety and reliability, I’d choose the wife.

  3. moneycone says:

    I agree! If the old car breaks down 60 miles from home, that is not a good spot to be in!

  4. Brenda says:

    I agree with FI Pilgrim. Longer distance has a better chance of a break down. I assume the newer car would get better mileage. That should be the deciding factor for the longer commute.

  5. Jacob says:

    What F.I. Pilgrim said. My wife always gets the better car, period. Safety and reliability trump all other considerations. :)

  6. eemusings says:

    We know all about being stranded due to breakdowns. So I would definitely drive the newer and more reliable one for the longer distances!

  7. This is an interesting question. Personally, I wouldn’t want a new car to drive, I’d rather have a reliable 4-5 year old car instead.

  8. I think the most reliable car should be used for the longer commute. In our family, my husband drives more than me. He gets the “family” car, which is the newer, 2007 Prius. I get the older car with a cheaper design. Of course, the Prius has way more miles on it despite it being 2 years younger, but it still is overall more reliable than my 2005 Aveo. If I break down, I’m usually within 5 miles of the house. If he breaks down, he could be like 30-60 miles away. AAA helps us feel secure too, lol.
