I would sell the car, and buy the KMP. I doesn't sound like the car does it for you anymore, so it's time to move on. You could put a buttload of money into it trying to make it more user friendly, but in the end you still may not be happy.

Also, think of it this way... While the value of the Mustang will continue to go up, the health of car will continue to go down. It may be nice now, but years down the line you'll get rust come through the body again, not to mention what happens to floor pans over time.

Glass or alloy, Cobras don't rust. Get yourself the Cobra, and enjoy it for the rest of your life.
