THIS... 100%.
I vote for letting go of the Jeep especially if you've got an easy opportunity to do so. It won't be any easier if your economical fears become reality. There's a big difference between selling because you can and selling because you have to. Avoid the stress and panic. I think the fact that you're considering it with your family's future in mind is wise and responsible. If we were talking about a rare vehicle, I might be apprehensive, but the Jeep is easily replaceable if the future shakes out positively for you. I just sold a car because a friend wanted it, I hardly drove it yet I was paying for it each month. Not mention we had four cars for two people. No child on the way, but the adult in me knew I should seize the opportunity and do the responsible thing. Honestly, a month later, I don't regret it at all. I essentially gave myself a $500/month raise, shaved $1200 off my car insurance tab, and dumped almost $10k into my savings account. I don't live paycheck to paycheck, but the added cushion during times like these certainly makes it easier to sleep at night. My two cents...
