Lotsa luck! was there in July to see James Taylor/Carole King. Noticed the a/c was only pumping out air just above luke warm (115 F temps typ then). Went to Desert BMW..., 3.5hrs & $236, just to recharge the a/c. I will admit, they had done a COMPLETE inspection of my car, as the service man had found evidence of previous things that I already had fixed (oil stains from a valve cover gasket leak).

Given your list, I'd bet you won't get out of the dealer for less than $800, probably more.

What's your mileage? If 100k, then the complete tuneup is due. If you are doing short trip & stop'n'go rushhour (a true oxymoron) driving, then fouled plugs are most likely the culprit. I'd go with that first and see what that does before investing in the rest.
Good Luck!
