Forget eBay, Craigslist, Barrett Jackson etc.
What (if any) is the price point you have at which your hand over the keys and sell the car?
There's a real difference between what my car would sell for vs the value I place on it.
The magic number for me for the past few years is $75k. I estimate I have well over 2500 hours of work into the car over the last 6 years. I'm afraid to add up the total amount invested, but I'm sure it's north of $35k.
At $50k, I'd think long and hard about it. At $75k, it's gone.
You?
