Honda SP2 prices - only going up?

As per the title. Do those with better knowledge of such things think that late, low mileage, excellent condition SP2's will continue to rise in value?

I've got one just like that albeit with 4k miles MrB, hence interested in people's thoughts as it isn't getting used.

My original plan was to buy a cosmetically rough, leggy SP1 and ride it. By accident (4 years ago) ended up with a mint 07 3k mile bike.

Thinking I should keep it and now go find the leggy one I originally wanted!
