I know there is a sucker born every minute but who on earth is going to pay $4K for a refreshed 1st gen Focus?
If it's worth $1250, offer it to CarMax and see if they'll pay a little more. Private Party maybe $1,500. But if CarMax will give you $1,500 take it and run.
It will depend what car/truck/suv you want because some have sizable rebates (and dealer incentives). Cars Direct is a good source of what's happening, also Lauren Fix on YouTube has talked about some rebates/incentives on popular models every Friday.
What vehicle do you want?
If you are suggesting CPO's, I would wait a little longer there is going to be glut of lease returns over the next 60-90 days.
Also Hertz while not the fire sale some have wanted to happen, none of the less they are discounting heavily some of the cars in their fleet.
95k is rarely "end of life" for today's cars. What do you think is about to go wrong with it?
I have trouble wrapping my head around the notion that it makes more sense to spend 20x as much money on another car vs. a $1k repair or whatever. Especially when you're underwater on your loan.
I'd get right on this loan, pay it off, and start saving up for the next car and be in a GOOD position when that time comes.
