When it comes down to bread vs toys, eating wins. Shelter wins.

Unemployed for a year means measures must get drastic. While it's unfortunate to sell the Crossie, I can't see it as being a practical car in your current conditions. If you get a job a week from now, keep it and sell the other two, and pay the Crossie off.

But, if you know that the job scope isn't improving, try as you might, then it's time to cut losses and rid the Crossfire. The Miata is cheap but impractical. The Riviera is cheap and practical, but unreliable. You need reliable... if you get a new job, it will pay dividends to arrive every day, not when the Riviera lets you.

I had a 95 Riviera, it was a wonderful car (when it ran). The 96+ cars were much better on reliability.

I'd off the Crossfire and go from there. Determine which of the other two cars cost less to maintain, and keep that one. It stings to sell the dream car, but it stings more to go bankrupt while driving one. No one is impressed then... and you're still starving.

You can sell the Riviera and buy a cheap set of steel wheels and snow tires for the Miata. Two 40# bags of sand in the trunk, and keep on trucking. When the weather is better, put on sportier tires and get your permagrin back. Then you have a stress-free, paid off sporty car that is reliable but not a turd. Never worry about parts for the Miata, they will always exist. Riviera parts are like the Crossfire ones... rare and expensive.

That's the thing I'd do if in your shoes...
