I own a 1998 Ford Explorer and there are major problems with the engine. I thought i just needed to replace the catalytic converter, but it turns out there is more and cost equates to about $1700. I still owe about $2000 on the explorer. Should i wait til the Explorer just goes dead on me and then buy another car to save on having 2 payments, or should i try and trade this one in where i bought it and refinance another car. If i trade in where i bought it then they will cancel first loan and just create another one. I don't want to buy another car from them, but i also don't want 2 car payments. I also own a paid off 2000 Cadillac Escalade. What should i do?
