Whatever you buy, at that price point from what they were you're always taking a massive risk, but you knew that before you got in. Sometimes it pays off (for the most part, I'd say Rich has been very lucky with his XKR), and sometimes it doesn't. It's at what point you quit and just accept that throwing money/time at it isn't reaping any rewards.
Stick with it Ricey. Go back and read your posts when you first got it, and remember how excited you were. Remember how good it can be, and that this is just a blip in the road. It's an awesome car, it would be a shame to see you move on from it so soon.
