What to do with my 560SEL?

[GradyService]

The 86 560 has been sitting on the sidelines this year, due to the hot and humid spring and summer here in NC, and the fact that I have yet to repair the AC. In fact I have been considering selling the car. I am in a new position at work, and it involves much more driving than before. Not that I mind putting miles on the MB, but It needs some reconditioning before I put it on the highway daily. I have read a lot about the W140, and have figured out that they are basically money pits. Don't really want to go back to the W124, and don't like the looks of the W210. So, that leaves me with the W126, which I have, which I like, and if I am going to have a 126, it will be this one. Black on gray leather, top of the line model, good interior, decent paint, only 154k miles. But the to do list is fairly long, too:
AC Compressor, Expansion Valve, and Dryer replace,*
R&R Left lower ball joint
Recondition both side's guide rods
Change valve covers and gaskets*
Replace Transmission Pan and Gasket, as well as Vac. Modulator with O-Ring*
Replace Antenna Mast
Have bumpers resprayed
Have dings pulled out of trunklid and front fender
Have exhaust system checked out
Change spark plugs, and fuel filter*
Flush Coolant and replace hoses*
Change oil and filter*
Replace fan belts.*

In addition, I don't know if the timing chain has ever been changed or not. I mean, she runs good, drives good, sounds good, but I have yet to check over the chain as is mentioned in one of the tech articles. My question is, do you guy's think that in the long run she is worth all of this? And do you think after all of this is done, she will be a "reliable" daily driver? (Items with * beside mean DIY).

Thanks, Dave.
