I agree with using a single car for a household: my wife and I have done that for the past six years (living in Tennessee, Oregon, and Arizona) with a 2006 Toyota Highlander that we paid $7,000 in cash for. The last two years, we've had a baby/toddler. We've encountered a few (one or two per six months) situations where we might have _preferred_ another vehicle, but the inconvenience was so minor (I Ubered, or someone picked me up) that another vehicle couldn't remotely be justified. Recently we got a beat-up F-150 to haul lumber and soil, but don't use it day-to-day and have never _needed_ it as a second vehicle.

Regarding the sub-$5k car: it depends on your definition of "decent used car." Most people are unwilling to accept a used vehicle with a slightly broken interior or other minor issues. Just today, I was looking for comparative prices for a 2003 F-150 that I've got, and I found multiple in the $2-3k range in my area that are in good condition (running motor, A/C works, non-necessary repairs required). And that's a pickup truck: if you want a coupe or sedan, there are even more options below $3,000. You just need to be willing to accept some flaws: right now I've got several tabs open of good "A-to-B" cars with under 200k miles.
