Do you both work and do either of you work from home? Is your work relatively 'close' to where you live? Ever considered becoming a one car family and commuting either by bike/foot/public transportation? If WFH you likely don't *need* two cars anyway. Even if you both work and don't want to commute by bike/foot/public transportation, you could work out a schedule to pick each other up; especially if either of you work and it's "on the way" to the other. Seems you've sunk quite a bit of money into the Taurus though I would be interested to know how long you've owned it? I probably sunk quite a bit of money (well into the thousands) into my old 93 Camry (which has been donated as of several months ago). I was 'gifted' the car back in 2005 though, at which time I certainly wasn't subscribing to any sort of "Mustachianism" even if it officially existed back then. No excuse for dimwittery though, as I could have saved tons regardless when I was younger, especially on car expenses. I digress... this reminds me: if you do consider getting rid of the car, you may want to consider donating it depending on the condition of the car and resale factor. It might not be worth the hassle trying to deal with selling "as-is"
Also, I concur with what others are saying: don't get *another* SUV - there isn't really any good rhyme or reason to. Just get something like a cheap used Honda Civic, Toyota Camry or Toyota Corolla if you need something 'budget' friendly. And of course, make sure to bring your mechanic with you or meet the seller at your mechanic to get a once/twice-over done on it
