IMO, keep the vette. Sell the third car and take $1000 to a Buy Here/Pay Here dealer and put that money down on a $2000 or $2500 car and pay the beater off $200 a month. That's what I did. Two years later, I still have the beater.
I do agree with others about her maybe having some issues with the car. I know my wife would never ask me to sell the vette. It would be my idea first. Besides, she has her own set of keys and if she ever said that, well, I would just tell her to sell her Harley.
Good luck! In the end, it's all on you anyway.
