You're going to love it. I'd disregard the nay-sayers who tell you it is tantamount to sacrilege to sell the pano separately. I took the same flak for doing it too, but I actually came out ahead in the end. Don't get me wrong, the pano is alright, just not all it's cracked up to be IMO. If you ever have the urge to slap a hard top back on it, the aluminum ones are easy to find. Personally, if I want to see the sky in a cabrio, I will just drop the top. Amazing how many people leave those hard tops on and never take them off.
If you have a very strong reason to sell off the cars original equipment, then so be it. But I'm for keeping these benz as close to original as possible. I don't like the 5 spoke AMG wheels that came stock with the Sport Option on my SL myself, and I've replaced them with R230 wheels. But, I'm keeping the original equipment wheels to go with the car, should I ever sell it.
As far as the looks or aesthetics of a Pano, it's a personal choice, and no one is wrong, it's what you like. At certain angles, I think the metal top has a better look, where the Pano has more of a R230 line to it... but again it's very subjective, and I'm not trying to sell the Pano on it's merits, just the ability to keep a complete car intact if you have the choice.
Money wise it could make more sense to sell it and pick up a metal top cheap, seen them as low as $500, but after you get the paint and interior right, that investment may not make sense either.
Anyway, I had a great ride home tonight, feels good to get the SL back on the road in the middle of winter for a day or two. Back into storage this week-end...
