Newbie m/b owner 87 560sl questions

[jetnoise]

Hi
New to the M/B world, just purchased an 87 560sl. Was driving it this past weekend and was amazed with the attention it created.
Any how it has 115k mile on the clock and after reading many post on this board I was hoping some one could offer some advice on waht to do to the car at this point in it's life.
Is it correct to call this car a 107 body style?
Here are some of the symptoms
R rear wheel locks up.... NTB wants 2k to replace everything
some new calipers hoses rotors pads?
Anti lock light stays on..broken wire on sensor or dirty/bad sensor??

Ride isn't very smooth....new bilsteins subframe mount kit, engine mounts?
S L O W power window motors
Engine idles high ...hate to put into gear. i have ordered an idle control valve

a/c doesn't work..after looking at other post maybe a t-stat switch?

I am working with my dad on this car to give it to mom to drive, so safety and comfort are paramount.
Could some one help put me on a good path to restore this car to its former glory? Any heads up on around the corner issues appreciated
Thanks in advance
Jim
