Sell the car, but tell the person buying it that if they ever decide they want to get rid of it to offer it to you first. Its sad when you see the type of car that you had and loved and got rid of. Its sad every time. But you may be in a much better position to own that car again in the future.

Thats my plan anyway. I bought my car before I could really afford it, and it screwed up a lot of shit for me. I plan to be totally debt free, minus a house payment, and have a big down payment next time I pick up a dream car.
