If I was sure that it would become a real collectors Item I would feel more confident it getting it. Also,it might cool my wife down.
If I may chime in here....
The "collector's item" stuff has come up before so here's my $.02 worth. There are only a very few HD's built in the last few decades that will ever really qualify as a collector's item until they get much, much older. There are simply too many examples of most of them. Now sure, if you kept any bike in mint condidtion for say, 50 years in your basement, then it might resurface as a collector's item, but that means you haven't ridden (enjoyed) it. You could do this with darn near any motorcycle, but only your heirs would get any benefit from it, and even then, you'd be better off investing the purchase money over that time and leaving the funds to them, instead of the motorcycle.
103thunder has an example of far and away the rarest CVO ever built, the blue flame FXR3. Open message to Brian: "Are you going to put that thing in your basement or ride and enjoy it?" I have a feeling, he's enjoying owning it, which means he rides it.
I will admit, that if I was amazingly wealthy, I'd have some dream garage with bikes and cars in it, ones that I just plain like regardless of collector value, that I'd just polish and look at and get a kick out of owning, but unless I win the lottery.....
Me, I pondered this sort of question several years ago before I decided to "Screamin Eagle-ize" my FXR2. Leave it stock or have more fun out of owning it? I went with the fun and I've never regretted it. I keep putting miles on the bike, and I know the more it has the less market appeal it will have but hey, I've enjoyed having it, and I think that if the mods are done right, the appeal in the market might shift but not necessarily go down. Bottom line right now is re-sale just isn't part of the picture.
So after all this rambling, I would say that on the one hand, $12500 for a FXR2 is a premium price. On the other hand it only has 2200 miles on it, which is quite low. Back to the first hand, at some point, low miles means it has probably sat for extended periods--the gaskets for example might need replacing from age. How are the tires (dry rot)? As with anything, things are only worth what somebody else is willing to pay. What is this bike worth to you?
I'm the second owner of my FXR2. It had 13K on it when I saw it. I was looking for a rider that had around 5K so I hesitated at the mileage, but I've since learned that, properly cared for, these things can have very long lives. Besides, many moving parts and gaskets were replaced later on when I didn the motor makeover so I effectively re-started the life clock. Puts a "*" factor on the mileage showing on the odometer.
Oh, and one more thing. It's NOT worth a divorce.
Good luck. If you buy it, by all means come back and tell us about it.
