My sons new ride, '86 300SDL and some questions.

[muleears]

Pics are in next post

I should have waited for the frost/dew to disappear, the paint is spectacular. I'm not crazy about the 17's but it rides ok. 194K on working speedo. Started instantly with normal glow at 31* this morning. I has a small amount of rust along the front edge of the sunroof and on the bottom of one of the doors. That is all I can find.

Now to what I need to fix:
1. Slow shut off- shut off valve or other vacuum leak?
2. AC doesn't work- told it was a leaking hose, seller was honest about everything else... we'll see.
3. Mild play in steering- ball joints? Maybe tighten the steering box? No unusual tire wear.
4. Belt tensioner noise- Tensioner and shock already ordered.
5. Runs COLD. 175 mile trip never got to 60* on the gauge. Already ordered a new thermostat.
6. Cruise doesn't work- Probably won't fix
7. RF window won't work- checking switch this morning.
8. All fluids/filters will be done ASAP
9. Needs shocks everywhere.

Any comments on my tentative diagnosis are welcome.
