Not trying to devalue your PANO, (I beleive your asking price is in line with other recent asking prices), but your statement about the option 415 cost when new is off quite a bit.
I don't have a window sticker for a year 2000 R129 w/PANO, but I do have a window sticker for my 99 that came from the factory with the 415 option.
See attachment, it was a $3695 option when new and buying it with the car.
What anyone would pay for a new one as a single part I have no idea, presumadly a lot more.
But I doubt that very few PANO's were purchased outright from Mercedes, I would bet most if not all that are for sale, came as options on a new SL.
So, if used PANO's are routinely being sold for $2500, they are being valued at about 68% of their cost as an option.
If only the entire SL would hold value anywhere close to that we'd all be very happy...
Anyway, good luck with your sale, hope ya find it a good home...
Figured I would offer it here first.
I have a panoramic hardtop roof from a 2000 500SL for sale.
Its never been painted. It has no scratches. Its color is Brilliant Silver.
Also, the headliner is in mint condition.
This was a $10,000 option in 2000.
I was going to put it on eBay for $2500, but, I am open to offers.
Would rather sell it through this forum. Let me know if you know anyone looking for this rare find.
