Again, welcome! I just drove a '09 350 last week, and I have to say it's a step up from my '06. Same comment on COMAND (P1 package) - it's absolutely a step improvement on the "older" versions - and would be a "must have" in my book.
The one I drove had the sport package and the AMG appearance package as well - it's a demo car for the dealer I visit for my C Class. I've always liked the AMG looks, but was not 100% convinced that it looked "better" than the standard "facelift" versions here in the UK - I *think* it was listed on the sticker at 2,600 GBP.
This one had the 7G transmission, but it's available as a 6 speed manual here are well - something I'd love to try out. The car was loaded - Bi-Xenon, COMAND, airscarf, heated seats, metallic paint, leather, phone kit, park-tronic, upgraded A/C controls, plexi windscreen, mirror kit, heated windscreen wash - the list was literally everything as nearly as I could tell. They were all individual options, not packs - I think it was about 10k in options total.
Sticker on the car was right below 50K GBP, and it was my salesguy taking me for a ride, so he knew I was not going to buy it, but he said that they are not dealing on these at all. Also said he's only sold the 200K versions so far.
All I can say is that spending $100k usd for a 350 - and yes, I still think in dollars - is absolutely insane. I guess given that they had an SL63 in the showrooom for 121K GBP it's not such a bad deal!
(and yes, I did leave drool marks on the SL - even though I think I prefer the pre-facelift looks..)
